So I ordered fuel injector adaptors from zzp. They were easy to install and everything but when I started the car I found that 3 out of 6 cylinders were having a misfire. I disconnected the fuel injector adaptors and found that the pins inside the end of the adapter weren't long enough to make a connection.
I emailed zzp customer service on July 13 to advise of the defective product. I received a response from Rachael who advised she would ship out replacements same day and I didn't have to send back the defective ones. As of July 20 I hadn't received the new adaptors. I emailed Rachael again asking if there was a tracking number. She forwarded my email to a Henry Cheng who said that he doesn't know what happened with the shipment, but he will send out the new ones that day.
I email back and ask if he at least sent it express shipping so I get it sooner. We then get into a back and forth series of emails where he tells me my order was "very old", it was from the end of March (3 months), that if I want faster shipping I have to pay for it and that I am throwing a fit because I'm not getting my way. I tried to explain to him that I just think that they should be shipping the item to me at a quicker speed considering they made an error and didn't ship it out 7 days earlier like they said they would.
After he was so short and told me I was just complaining because I'm not getting my way, I then told him that I didn't want to receive anymore emails from him. He replied with an email at close to 9pm central time saying I should go cry a river. I don't know if this guy is the owner or something but I don't know why he thinks he can talk to a customer like that. They have definitely lost a customer and I would recommend anyone who wants to order from there to be cautious. Check the w body store first or other resources.
