See postings for 920-268-1691. The caller using SMS spooling to fool the caller ID. These people are scamming. First state they are calling from Peter Thorpe office and when that didn't work they called saying they were from John Hendricks office.
They claim to be a marketing firm of some sort, only they don't provide specifics when asked.
I don't know what their end goal is. I do know they are annoying with their persistant calling.
