I was calling CISCO for Windows upgrade unbeknownst to me after person telling me he can help etc when we proceed it was iyogi. They double charged me for a product I couldn't use. They, after much argument, gave me a refund minus $25.00 shipping fee & had to pay $25.00 to return ( those fees a rip off) Then I discover they billed me twice. When I was paying they said the charge didn't go through. I thought that eas odd I have a zero balance. I'm questioning them about this and a different person (supervisor) and tells me it didn't go through. I give another card. This happened 2/27/15 I still haven't received the refund. THE AMOUNT OF CALLS, HOLD TIME, ARGUING, PROMISES. I am their worst nightmare cause I'm not going away! DO NOT USE THIS COMPANY THEY ARE CROOKS!
