I believe this number as well as many others is MRS debt collectors! I've received calls from them from 856-335-5527 - 800-932-5573 - 856-335-5527. When I track the numbers from this web site I always come up with MRS. I have a phone system that allows me to block these kinds of calls. Eventually they will come from another number, today it said unavailable. Once again they've been blocked on my phone system. You wonder just how many phone numbers they're allowed to have!!!
Called my office number. I have 4 lines - the main is the only one published and it rolls over to the others if the line is busy. I have a client who comes up as UNKNOWN because he calls from out ot the country. This "unknown"/856-673-3706 called four times right in a row without leaving a message and made all four of my lines busy. Good thing this was before my normal working hours begin.
