This caller comes up on my Caller ID as AT&T. However, they never leave a message, and they usually hang up when I pick up the phone. I picked up the phone this morning after I have been receiving numerous calls from this number, and before the caller could say anything, I told that person NOT to call me again and to remove my name and number from their calling list. I also told that person that I am sick and that am in a great deal of pain and getting up to answer the phone for calls like these is an unnecessary burden. Then, I said "Thank you" and hung up. After that, I got 3 or 4 more calls this afternoon from the same number. Unfortunately, I have been getting similar calls, also identified as AT&T, from (205) 216-4883. I just told the caller from that number yesterday not to call me any more because I am sick and in pain. I also told them to remove my name and number from their calling list. This morning, I started receiving calls from the (702) 673-1108 number. This must be the same outfit, using different numbers. It's very hard to block them this way. I'm thinking about blocking ALL numbers and just allowing the ones from people I know.
