Called inquirying if we accept credit card. Then wanted to know who would she talk to for a review of our current processor. I told she could not talk to anyone for that purpose but that she can talk to me and pay for our services with her credit card and is she wasn't interested in that, then  to stop calling and wasting my time.

Got a call from this number at my business. Caller ID came up BLUEPAY. No one was there, just dead air. I hung up.

no message- calls repeatedly all day long

Hang up call. Assumed to be a telemarketer. Or, perhaps they realized they had called a number on the "Do Not Call List".
Either way, get lots of these unsolicited supposed scams. They use various numbers from around the country. Some may be legit, but, I suspect most are con-artists. Many are even just recorded messages offering government grants, etc.
Others have claimed "I" had filled out an application for a loan.
They have been reported to the NC Attorney General.

I get so many calls from telemarketers that I let everything go to voice mail unless I know thw number.

Cold call from telemarketer trying to obtain information about the company's credit card processing services. Caller hung up when he was asked to give the purpose of the call.

Company is BluePay.com, and they are offering purportedly lower fees for credit card transactions, for businesses.  They called into a number that is on the Do Not Call registry, so they are in violation of federal law.

The caller is a solicitor for a credit card processing company that offers their services to businesses. Call back and press 3 to be removed from their calling list (supposedly).

business solictor for saving you money...recording when you call back
