Same thing. Drives us crazy. We called the Startech 1-800 number from their website. They promised us they have removed us from their call list. I really hope so.
This number has called me for the last 6 months at least 3 times a week. Most of the time I don't answer. When I do, the caller is Spanish and when I ask him to speak English he hangs up. Caller ID says it is from STARTEC.
