Customer support experience

September my account gets restricted because of lack of good faith searches. I read the terms & services & follow the rules, checking back with support every couple of weeks. January I had enough, deleted Bing, and stopped using it altogether. The 28th of February I contact Rewards support asking why I am still restricted. They say lack of good faith searches. I tell them I haven't opened Bing since January. A week ago they say the gift card I am trying to redeem is out of stock. I tried redeeming every thing in that catalog, still can't spend points. Today that reply saying that their end doesn't show me spending points, so they are closing the ticket. How does that make any sense? What is left for me to do? I couldn't afford a legal case if I wanted to try to make a lawsuit out of it. Should I just give up and let Microsoft do me like this?
