Hello, I have purchased a black LED strip, power supply, and LED controller from a seller and I received a white LED strip ( I need a black one to match the color.) I kindly requested them to send me another LED strip that is black this time and they did. But the LED strip doesn't even work. I contacted them saying "Hello, the led strip is not working when the others connected are. I have decided that I want a refund as I keep getting problems with this product. If I do not get a refund, I will open a dispute with eBay." they responded with "could you please give me a picture for the power supply details ? it seems the power supply is not correct for the strip" so I said "yes, I am 100% sure. it is working with one led strip but not the one you sent me. I don't want you to send me another power supply, I want a refund please" they ignored that message so I sent another - "You seem to be ignoring my message now. if I do not get a refund within 48 hours, I will open a dispute with eBay as I keep getting problems." It has been over 48 hours with no response so I went over to refund it and I cannot because I have already opened one for this product ( them sending me the correct LED strip ). Please resolve this and get me my money back as I don't want to get scammed. :)
