After purchasing Windows 10 from these guys & posting a review about the fact that I had problems with installation & how helpful they had been, I received a call from a scammer impersonating a customer support person from Microsoft. They said they knew I was having problems & they were here to help. I thought "Wow, what fantastic customer service!" They then requested that I use "team-viewer" to allow them to "fix" my Windows 10 problems. Then, this very professional sounding person (who knew my name & phone number), hijacked my computer & I was told I would have to pay them by credit card to get my folders back. Coincidence?? Maybe. Not that I think it had anything to do with these guys but maybe someone reading these reviews. I didn't have anything on the computer worth paying for so I simply disconnected it from the internet. Later I deleted the Windows program & reset the computer back to imac settings & I haven't turned it on again since. Anyway, beware, because not only didn't I end up not using Windows 10 & therefore wasting my money & but I also ended up with a retired computer (for the moment).
