I was trying to have them build a computer for me. I supplied them with a parts list. Throughout this endeavor I have been lied to on prices and they have been trying to scam me out of my money. The parts list I gave them was quoted at $2500 before warranty and taxes. With taxes and warranty $3000. I was quoted it was going to cost me $5000 for parts and warranty before even it was built. They pushed this idea at me and after looking it up and calling them back about to state that the actual price should be $3000 they said they made a mistake and put everything as quantity 2 yet they pushed for 5min straight saying that its because the parts are from my distributor and that they are coming in asap so its rush shipping fees and that computer prices fluctuate but after I tell them Ill look into it and call them back they change there story. I was finalizing the bill and they quoted to me that it would cost $3000 for the computer and warranty and everything. So I came down and he started adding hidden fees in and the price went from $3000 to $3900 and yet that wasnt what was quoted to me. He tried only reducing $200 but I explained that I was quoted $3000 and If you forgot taxes then I can understand $3300 but no more. He adjusted it down to $3267. I asked the estimated time that the computer would be done he said 3-4 business days and we are currently on 9days of work. I am now trying to back out of this deal because I feel as though I am being scammed out of my money and they still havent worked on my computer at all because they require further payment from me when I have document saying its paid in full. This business is extremely sketchy and isnt what is says it is so I need assistance please i dont want other being scammed out of there money like they are trying to do with me and I dont know if you can help with this but I want my money back sense I havent even gotten any product from them that I paid for.
