MAINGAU Energie GmbH Reviews 

Not possible to register into Maingau app for people having an address outside Germany. So not able to use the full functionality of this app. Frustrating. I want to claim my €9,99 back

Inkompetenter Kundenservice.
I filled out their moving form (Umzugsformular) but they incorrectly created a new internet contract for my new address so I paid double for over 3 months until I noticed the extra charges.
I then reached out to their support team, which seemed quite effective and promised me a full refund in the next bill. However, once the new bill arrived, the amount that should've been refunded appeared as an extra charge. I blocked the SEPA order and got an automatic email asking the incorrectly billed amount to be paid in 3 days or extra fees would be charged.
I've sent over 5 emails now but they are only responsive via phone calls. They have refused to speak English in 2 out of 5 calls. They also hung up on me in another call as I was explaining the issue.
After managing to speak broken German in one of the calls they appeared to understand the issue but decided to apply the owed refund on the bill that was listing the refund as an extra charge - therefore giving me no refund for the mistake they made by creating a new contract when I moved.
I have now sent them one more email saying that if the problem is not solved I'll have no option but to contact Schlichtungsstelle der Bundesnetzagentur and Verbraucherzentrale. I can't understand how they try to get away with ignoring emails and miscalculating customer bills after multiple mistakes on their side.

After you sign up, the company makes themselves completely unreachable. Their "AI" assistent answers the phone, and it is incredibly effective at keeping you away from any human operator. I then tried writing emails to the so-called "customer assistance" address, begging for a phone call: I never once got a response other than, "we received your message; someone will get back to you. An exercise in total frustration when you really need help. What a horrible company.

When the collection from your payment account fails, they immediately charge you with a so called "Rücklastschrift". I refuse to pay these costs.

Never received the charge card.
They don't reply on email.

Used this card once for my eGolf at my employers charging station. 27 Euro instead of the usual 4 euro. High fees AND 10 ct per minute standing fee.
All this money goes to Maingau. My employer invests and Maingau makes hughe profit.
Stay far away from this provider!!!!!!!

STAY AWAY!
After 4 weeks I am still waiting to have my DSL installed.

No contact, no emails or calls are answered.
Not sure if this company is not a complete scam.
