who is calling from this number

I answered the call from this number, was an automated voice message saying they are from "cardholder services" but didn't mention for which company.  Scam.  Avoid.

This number called earlier today on my cell phone. It went to voice mail and they left no message.

I got a call from this number this morning. As I didn't recognize it, I sent it to voicemail. No message was left.

Got a call from this number claiming it was card holder services and to press 1 to lower my interest rate.  Did not say which company.  I pressed 1 out of curiosity.  The woman who answered said she was with card services.  I asked which company and she said they work with Visa, Mastercard & discover.  I asked if it was telemarketing and she said no and asked which card I had.  I said I wanted to to tell me who she was calling for so I can verify she had the right number.  She said she looked me up in her system and repeated back my phone number.  I asked her to give me my name and she was unable to.  This is a scam.  Do not give them any info.
