A residential phone customer received calls from unknown callers who asked for them specifically by name and were given their home phone number to call for diabetic supplies.  The 484-369-5200 is the number that is coming up on caller id.  For example, Mr. Jones receives a call from 484-369-5200 they state that if they are in need of diabetic supplies to call Mr. Smith at (Mr. Smith's home phone number) of course Mr. Smith is retired and has nothing to do with diabetic supplies.  Who ever is making the calls knows a persons name and their actual home number, kind of scarey.
