Imperial Automotive, Car computer exchange Car Computer Exchange sent back car computer and have not received refund for bogus ecm Cary North Carolina

2/5/19 purchased computer from car computer exchange $388.95 , received ecm it was painted back no calibration codes visible, installed ecm and it did not work correctly. I called computer exchange and was told to return it for repair or refund, I chose refund.  It's now 4/2/19 after 7 + phone calls to them and being told something different each time by the same girl, who by the way gave different name each time, told me this AM that upper management handles refunds and she can't do anything about it, I asked for transfer to management and she hung up on me.

I have been doing a lot of background checking on Imperial auto and car computer exchange, I found numerous complaints about them and how they rip people off on return of defective computers. This place needs to get shut down. The only ones with access to really program ecm's are the dealers.

DO NOT USE THIS COMPANY THEY ARE A RIP OFF!!

I would like to find out if any law suits filed against these guys.
