THis number has been calling me 2-3 times a day for the last week. I usually miss the calls and when I do pick up, nobody is there. We have direct tv, so I'm assuming it's them. Getting annoyed!
Seems to be a third party contracted by DirecTV to schedule appointments. I should point out that if you call back, option 3 is to be placed on their do not call list.
DirecTV is trying to get you to add HDTV or other services for free because you are "such a good customer." The free period is temporary and you can cancel any time before you get charged in three months...or whatever period.
Basically, it's the official DirecTV sales department trying to get you to add service.
