Female caller saying it is a business matter and wants to verify who she is speaking to.  When asked who she was, would only say that it is a business matter.  Then tells you that you have a doctor bill that has gone to collection and it needs to be paid immediately to avoid being reported to a credit agency.  Hang up!!!  It is a scam!!!!  Do not give them any information or a credit card!!!

I keep getting phone call from this number it's a scamming
