Complaints about Phone Numbers412-968-####

Female person called and left a voice message on my cell phone. She said she was from Zoll [Z-O-L-L, she spelled it out], and was trying to reach a Mr. Waterford and this number [she did not specify which number and I have two other lines forwarded to my cell phone] was listed as "his sister" [she did give the name]. She was probably trying to get someone in area code 703 rather than 606. I get a lot of calls from Northerners from Washington DC trying to reach an eye doctor in Virginia. Who knows, but she was not available for a call back from me but I am sure that the business [Zoll] has caller id and saw that when the return call came it was from a particular business to which they did not want to talk to.
