Dieselogic L&J diesel Took my money after I returned there sub-par product Jacksonville Florida

I ordered a set (8) of diesel injectors in the middle of April. I received the injectors and installed them in my truck. I am a certified Diesel engine mechanic. After installing these injectors the engine ran far worse and had injector knock in 2 or more cylinders. I called the company and they said send them back and they will test them and replace the faulty injectors. So I sent them back and 3 weeks later I hadn’t heard a word from them so I called them and they had said that they had just checked the injectors in and out them in there testing queue.

Another week later I still hadn’t heard and called again. They said they hadn’t tested them yet. I damanded demanded if they weren’t tested by the end of the day I wanted a refund. They called me back later the same day and had said they all failed testing so they were sending me 8 new injectors. I received those a week later and installed those that weekend. I found that the truck ran a little better but still had injector knock in at least 2 cylinders. I then called again and they had told me the same thing as before. Seeing as how this is a 12 hour job minimum each time it’s done I decided that 2 times is enough and wanted a refund.

They told me to send them back again and they would test them and issue a refund as long as they failed testing. 2 weeks later I had to call once again cause I never heard anything. They had told me that all 8 injectors had passed testing and they would issue a refund minus a 30% restocking fee cause the injectors had passed testing. I know for fact that at least 2 injectors were causing knocking and the engine to run with a lack of power. I had argued that they were faulty and they told me there was nothing they could do. Finally we came to an agreement of a 15% restocking fee and that they would send the full refund minus the 15%.

They also owed me core injectors that I had sent them in the beginning. I have since received the core injectors but have not received the refund. I called and emailed after waiting 2 weeks and never got a return call or email. So I proceeded to file a dispute with the credit card company at the end of July. I just found out on September 4th that the credit card company had favored the Merchant because this company said they credited my card $69.50 on April 29th. They credit on April 29th was due to back ordered parts that I had ordered with the original order of injectors. I told them that they can keep the backordered parts and send me a credit for those and that I’d find those parts on my own. I’m looking for my money back that is due to me for returned parts that were advertised as something that didn’t meet the standards advertised. I’ve since ordered a set of (8) injectors from AC-Delco and haven’t had any issues since.
