Request for removing the comment of the phone number

I have had calls from them after using a hospital in Florida. It is a 3rd party medical billing company. Got invoiced for services in early April in mid June. My Health Care provider had paid most of it so it took a while for the final bill. I called them back, invoice had the # on it. Looked like they have offices in MN and GA, but they sounded like it was a call center in India. I paid them so sooner or later they'll go away meanwhile I just send the call to voice mail ...and it disconnects.
