Who called from 2052081339

I have received three, maybe four, calls from this number.   It tells me to press whatever number for an operator, etc.  I want the calls to cease.  I call back and I get a busy signal.  PLEASE stop!

this is they say a way to decrease your credit card interest.....we don't have a cc or at least I think this is the company.
They call and give you the opt out option but it never works and I have asked who I have to sleep with to get them not to call and they hang up

Caller ID:  Unknown.  I did not recognize the number, so I did not answer the call.  No voice mail left.

no name and no message left.

When you call back, it asks you to press 0 to speak to a representative.  You press 0 and then it asks you to leave a message with a callback number.

Every night, a call for senior citizen.
