Auto Computer Exchange Will not honor the lifetime warranty Davie Florida

I purchased an engine control computer for my 2001 Chrysler PT Cruiser 07/26/2013. The module stopped working about 03/24/2017. I contacted them and requested a replacement module for the lifetime warranty and they asked to see the copy of the invoice which I never received one with the module. I contacted e-bay and pay-pal to see if they still had record of the transaction and they did. The transaction information clearly shows my name, address, date of purchase, make madel and year of my vehicle, the amount, the e-bay tranaction number, and Remanfactured with a lifetime warranty. All of that information was provided and they still refused the lifetime warranty. They are total ripoffs and buyer beware. It would be better to spend a little more and get it from a known good company. The only reason I purchased it from Auto Computer Exchange is because it was cheap and the lifetime warranty.
