GASGAG started a contract without my consent

I discovered that GASGAG stipulated a contract with me without my consent. This happened right after I had terminated my contract with another provider because I’m about to leave Germany. I really don’t understand how this could possibly be even remotely legal.

Your poor service It is difficult to contact to you

It is difficult to contact to you. We set up a direct debit of €25 per month, but then you immediately taken more than €100 from our account without any explanation. And we asked you to send a clear summary of our account but never received it. As a company of our energy, the service is very poor.

Guten Tag Lian Y.,

danke, dass Sie Ihre Erfahrungen so konkret schildern. Sie sprechen mehrere Punkte an: die schwierige Kontaktaufnahme, die Abweichung von der vereinbarten monatlichen Abbuchung sowie die fehlende, verständliche Aufstellung Ihres Kontos. Diese Hinweise sind wichtig, um unsere Abläufe im Service und in der Abrechnung zu überprüfen. Damit wir Ihren Fall genauer nachvollziehen und klären können, nehmen Sie bitte erneut Kontakt über unser Kontaktformular unter www.gasag.de/kundenservice oder telefonisch unter 030 7072 000 00 auf.

Everything is simple and easy

Everything is simple and easy. The response time for a complain or quarry is super fast and reliable. The connection price could be a little bit lower as compared with other companies in the market.

And least but last -- a lot of foreigner living currently in Deutschland. So if the App could support English language then it would be the best thing for foreign customers as well as it would suppress other companies dramatically in the market. That is my opinion.

I would not recommend this provider

I would not recommend this provider. Their systems feel outdated, particularly around automated payments, online platforms, and digital communication, which can lead to unnecessary complications.

Contacting customer support is also challenging, especially for non-native German speakers. Written inquiries receive responses from a “no-reply” email address, making it difficult to have any meaningful back-and-forth or resolve issues efficiently.

Aggressive Misleading Salespeople

Very aggressive salespeople stating they were sent by my Landlords. They would not take no for an answer and pressured me into revealing my Vatenfall contract no. despite me raising Objections on Data Privacy grounds. I felt like I was being scammed. It was a very uncomfortable situation. I feel worried now that their Tablet PC had my personal details.

GASAG AG is a scam

This very “nice” guy came to my door explaining that they are company who helps you change your current electricity bill for a lower and better cost. Since I already had a really bad experience with people coming to my door asking to provide personal information I said that I would first be interested in doing a research about the company and would contact them if necessary. The guy then turned from being nice to being a bit aggressive in the way of speaking, saying that it was his 3rd time in the area and they wouldn’t come back for me. I said ok, I’m not interested anyway. He showed me his tablet and I could see they have already written my name and some information, only missing my contract number from Vattenfall to do the change. Please do not fall for this, it’s a Scam from where it would very difficult to get out from. It’s my 2nd time with 2 different “electricity companies “. The first time I made it out thanks to blogs, reviews and experiences from other people but it took me more than 2 weeks, I almost lost my contract with Vattenfall and the people from that company was impossible to talk to. I had to fill a police report and send the kündigung to different emails and addresses at least 100 times until I got the confirmation.

🚨 Very bad experience with a GASAG representative 🚨

Today someone from GASAG came to my door trying to push me into a contract. During the conversation, I understood that I would automatically be sent a contract by email and it would only be canceled if I called them to say I didn’t want it.
This is misleading, aggressive, and feels like a scam.

Luckily, I refused immediately, but I find this behavior unacceptable. I strongly warn others to be very careful if approached at home by their salespeople.

If I ever receive something I did not request, I will also publish the full name of the person who came to my door :)

Hello, thank you for your review. The behavior you describe is completely unacceptable and does not in any way reflect the standards we expect from our sales representatives. A transparent, fair, and respectful consultation is our highest priority, and we take your feedback extremely seriously. We want to investigate this incident with the utmost urgency. To help us do this, could you please send us an email to kundenzentrum@gasag.de with the date and approximate time of the visit, as well as the location (street or area)? This will allow us to identify the representative and take the necessary steps. Thank you very much and kind regards, your GASAG team

I didnt had any choice about GSAG

I didnt had any choice about GSAG, some representative knocked my door and gave false information that my price will be reduced from my previous vendor . It was not clearly explained , I was shocked by seeing my first bill no amount was reduced so initially it was too tough to contact and change my monthly amount to customer care. I still not sure how my consumption will be calculated for my GAS and Electricity for the Annual usage .
