Auto call, message said was Card Services.  I pressed 9 to ask my number to be removed.  The person refused to remove my number and demanded my name and then started telling me to f** off, f** off, suck my d*ck, suck my d*ck over and over and over.

This number called me and presented a credit card scam to lower my credit card interest rates by 6%. When I pressed for a company name the caller said "Visa and Master" When I asked if I can call back if I would like to take advantage of the offer, He said "no, only now" When I said I would not like to do this today he said "F*** You - I will cancel your credit cards and raise your interest rate to 29%"

Received this call again.  I do not know who this is.  No one there when I answer.  Dumb me for answering.
