I was called by the number XXXX. I was asked to verify my name. I did. I asked who was calling. They did n't answer the question, but instead asked me to verify my social security number. I told them I was not giving some stranger on the phone my security number if they would n't even tell me who is calling. 

The caller ( a woman ) rudely said she would " mark on my file my failure to cooperate ''. She then hung up. 

I looked up the phone number on the internet and it belongs to Medical Revenue Services in Florida. 

" Failure to cooperate '' should NOT be listed in any file pertaining to me when the caller FAILED to identify their identity to me or why they were calling. I feel this is a fraudulent practice and such practices should be ceased!
