Don't rely on ECS Tuning application guide Based upon website guidance, I ordered an auxiliary input wiring harness for my 2003 Mercedes C240. I received it, decided to do some online verification before opening the package. I learned this harness wasn't compatible with my car's wiring. After a lot of hassles I was authorized to return it. I paid shipping both ways for a part incorrect for my car, despite the website claim it would work.

Nothing about this transaction went… Nothing about this transaction went well. Ended up buying elsewhere, saving $300+, plus free overnight shipping. Weekend staff online worthless to solve issues. update; BS. I was asking why my payment was not processing, why I had no bonus points, why I could not use the $25 off (which processed the last time I tried) and why I always have trouble signing in... you should at least have read the text. But guess what, I'll probably still have to use y'all since you have bought everyone who supplies BMW parts, etc.

Bought coated rotors that rusted in 6… Bought coated rotors that rusted in 6 months, In order to get a refund I need to purchase another set from them , I told them I would send them back and if they can return my money? Th Amanda there customer service manager, stated the only way is to repurchase again from them and they would issue a credit . There "HOME OF THE LIFETIME REPLACEMENT" IS A COMPLETE SCAM! I'M AFRAID IF I DID SEND THEM BACK I WOULD NEVER SEE MY MONEY OR CREDIT FROM WHAT I'VE BEEN READING ON ALL THESE SITES THEY'RE A FRAUD AND I NEED TO BE STOPPED!

Why is ECS still in business? Can anyone tell me why this company is still in business? I'll spare you the details of my story with ECS except to say they have no customer service at all. Further, I twice spoke to their sales person who twice forwarded my call to never answer customer service. His name is Michael. I'm considering filing a civil complaint. Obviously they know about their poor service but have chosen to do nothing about it That helps justify punitive damages in a law suite. What do you think the jury will think about all these reviews?

Just bad customer service They could actually order the parts and not lie to customers. I called in to order my parts, The website and the representatives both said it that the parts were in stocks. Everything that I ordered was in and it should arrive to me within 2 to 3 days. A week later I called to check on my order because I can't even find the email for the order, to track when I called I was told no one but the representative who helped me place the order could figure out what happened to my order. I talk to that representative and was told "oh the orders out. There was a delay I should get my order in the next 2 days. After getting off the phone I magically received my emails with tracking numbers. Telling me the items were just labeled. I would have Appreciate it the truth better than a lie that was back up by your own system.
