Oh I am so sorry! You have so many reasons to sue. I just last month got away from them. They would not refund my money and they would not break the link. I finally got some help the end of summer but they still were taking my photos from my phone. I just bought a new computer but I am thinking about changing to Apple anyway. I would not be lady if I said what I really feel about Microsoft. I am retired but was a Computer Tech and Microsoft and they used to be the one of the best, so sad to see how far they have fallen. I would consider a class action.
Very Very sorry about what you are dealing with. Absolutely inexcusable.
