Same is happening to me.
A daily call at the same time everyday.
When I answer it is automated; says "thank you for calling AT&T Solutions", some shpeel about being the nation's 4g provider, then asks me for the extension of the person I want to talk to.
They call our office constantly! Say they are from "AT&T Solutions" and want to speak with the owner of the cellular account. We hang up because it's a telemarketer.
