I have been trying to purchase a laptop from this website for well over a week now. I have gone through different credit cards and none of them have worked. I called my financial institution, there was no problem with the payment. It was valid. Nonetheless, it was voided by XoticPC. I had to wait to have my money back. Then, I tried again as suggested by XoticPC's poor customer support, and it was declined by XoticPC again. I have lost plenty of time among different customer support lines, and it has all been for nothing. I give up. It is IMPOSSIBLE to make a purchase on this website.
