First call from this number was trying to get info on my Medicare diabetic supplies. Person was not well versed on her info gathering. She was from a foreign country and was trying to  get my SS number by giving me the first five numbers correctly and the last four wrong. She claimed she worked for Medicare and was trying to find the best provider for my supplies. I told her that I was on an auto-fill with a company and had no intent of changing providers. I informed  her that I was hanging up, which I did. She called back, saying we were disconnected. I again informed her that I was not comfortable with her questioning and hung up again. I tried to call her number back and got a message that the number was not taking calls at this time.
