Don't buy from syngas

Don't buy from syngas
I purchased 3 syngas plug-ins and the company added 3 warranties which I did not order, a radar detector which I did not order and a tire inflated which I did not order.
I contacted them thru 34 emails before they responded for the address to send back the product for a full refund. I sent back the items and send them the tracking information but they still haven't refunded me the $192.81.
It appears on multiple reviews that they add additional items onto orders and its like pulling teeth to get them to respond let alone refund the monies due you.
I have since filed a complaint with BBB and filing a complaint with paypal.
I recommend not purchasing anything from this company.

To Roy at Syngas, My order number is
A30BCC9B54 (Maureen Flores)

This is a total rip off

This is a total rip off. The device does Not do anything closecto what is advertised. The Refund is a worse rip off. When you call in to get info on a return, they havecyou write a review. Then you call back to follow up on the return instructions. They Do Not take back an open or used item or refund you because it is used. Hello how are you to know know if it works or doesn't work unless you open it and use as instructed. Not Go There!!!

Exception service

From purchase to receiving product everything went exceptionally well. Confirming order to advise product on way. Shipping details & advise that product has been delivered. The only fault is mine because I over ordered. Now waiting for information about returning ONLY the over ordered . Just not quick in responding to me. At first I thought I was scammed. How wrong was I & for that I apologize. Just me being impatient

Customer Support

When I first purchased product, company support was quick to respond and address any of my concerns. But after receiving products, and wanting to return them, that quick customer support went away and my inquiries were now being diverted to AI and automatic responses.
