Complaints about Phone Numbers843-956-####

I received 25 calls from 843-956-4567 in one day. After the first call I told them not to call my number again. Then they started calling from 903-818-6371 from Texas. Then they started calling from Florida. You can tell they are the same people calling from a call center. All want to send you free braces to help your pain. Once they told me they would put me on the National Do Not call list if I would tell their supervisor that I had not ever received these braces. I told them I didn't want any more braces sent to me. I have asked everyone to quit calling me. This person said he would send out my new Medicare card. I told him I already had mine and he wasn't going to get the new number. He says he is with Medicare and the braces will be no charge. The more I ask them not to call the more they call. I had to unplug my home phone just to get some peace.
