OEMassive Bad customer service Hacienda Heights California

I purchased a pair of led tail lights for my Silverado. When I hooked the lights up the reverse light stayed on so I called OEMassive and the guy said I needed a professional to install and he was aware that the reverse light stayed on because wires were hooked up backwards. So why sell a product and not tell customers that the product was faulty from the start. The bolts did not line up with the factory holes either I called him back he said he would discuss with a professional and not myself I know I don't do auto work as a career but I have done enough to put some lights in a vehicle building and reprogramming computers wiring etc on 10 other vehicles in the past. The way he talked was very unprofessional and uncalled for. The light did not come with a resistor either and none of this was explained in the description as well as it only said professional intaller recommended but not demanded. So he lied and this is a business that lies and will rip you off please don't patronize this OEMassive business. ITS A RIP OFF FOLKS
