Got a phone call from this number, and just let the phone go off hook. Will try to call tomorrow at work to harass them. Planning to set my fax at work to autodial this continuously allnight

Got a call from this number- automated message telling me it's urgent that I press one so that I can lower the interest rates on my "current credit card account."  They're either selling something, or it's a scam to get you to give them your credit card info.  

This number keeps calling me with an automated response telling me that it's urgent that I press one to speak with a representative about my credit card.  I have asked to be removed from their calling list but they keep calling.

this number is a scam hang up DON'T  press anything

Got 2 calls in 2 days offering credit card interest rate lowering.
Didn't identify institution.
I think it is a scam to get  your number
