Who called from 2532468509

I keep getting calls from this stating "last chance to reduce credit card rates". When I ask to speak to a supervisor they hang up on me. Since I have not Credit Cards because I try to pay in cash I know these people know nothing about me. Therefore it can only be scam. If anyone can get more information on this company I would appreciate it so that we can inundate them with calls.
When I said yes I would be interested and asked them for more information they hung up.

Another call from the credit card interest scam.  They just keep changing their number.  I press 1 to speak to a person and then I just put the phone down in front of the radio that is turned up very loud, until they hang up,.  This works for a while.

I saw call was made to me so I called number & got message its not a valid number

Called offering rate reductions -  own no credit cards.  Hung up on me when I said that.  Called number, out of service.  I am on Do Not Call list.

I received seven calls from these [***] today. i am ready to hunt these mother f*ckers down and shot them in their mother f*cking faces.
