I answered a call from this number this morning (Monday). A woman said that I had my heater inspected two years ago and it was time for another inspection. I said I didn't recall ever having the heater serviced before. She said there were two other phone numbers linked to my service address and one of them had paid for the service the time before. I said she should contact them and they could call me. We were disconnected in the middle of her next sentence or maybe she just hung up. I suspect this is a scam as I've been at this address for a dozen years and have never had the heater serviced.  

650-948-6269 was disconnected over 5 years ago.  I called ATT and they said that they cannot do anything about a disconnected number.  I have sent several e-mail messages to the Reverse Telephone Lookup.   I would very much like to know how to make this stop myself.

I reported to PrivacyStar that this telephone number was disconnected 5 years ago.  ATT says they cannot do anything about a number that has been disconnected.

This telephone number was disconnected five years ago.  ATT says they cannot do anything about associations with prior with telephone numbers.
