So a little while back I was swapping out my amps and all was going fine up until I got to the RCA's that I got from KnuKonceptz. When I tried disconnecting them they were a little stiffer then usual so I let up on the force and began to try slowly twisting them out and next thing I realize the prongs just snap and get stuck in the amp. Now I know this is probably due to the cold and them being plastic but I'm reviewing the customer service not the wires themselves. So after that disappointment of breaking a pair of RCA's I go to my sub amp and guess what, same thing happens. So now I'm out two pairs of RCA's and not sure what to do. I go to the KnuKonceptz website and see they have a 1 year warranty on all their products so I'm relieved and try sending them a simple email, explaining to them what happened and including my order number, phone number and everything relevant to the issue. A couple of weeks go by, I believe two and no reply from KnuKonceptz. I send another one trying to touch base and see whats happening over there and if I'm going to get a refund/exchange or what have you. Wait another week and still no reply back. I'm 100% sure it is the correct email as I've triple checked and copy and pasted it into my email. Now I resorted to calling them and getting an answer from somebody. I've tried calling them before, but during the holiday season so I never got a hold of them because I assume they were just very busy. I went into this phone call with pretty low hopes of contacting them and after 10-15 minutes of attempting to call them I gave up on that cause. I'm very disappointed with this experience I've had with them because everyone is usually raving about their customer service and how amazing it is. I wish I could at least get a response from them.. About to buy new wires from them, probably the Krystal wires as those would be a step up or resort to either filing a PayPal dispute to get a refund and get their attention.
