Very very sneaky! They wake you up early in the morning on the weekend then hang up. They call you consistently at you job then hang up. They call you hang up then call you again when you least expect it. If this is behavior indicative of Sirius I urg everyone to drop their service immediately and show them whos boss. I previously dropped them for withdrawing cash from my account with no prior authorization. Perhaps their angry that they don't have power over my finances anymore. Beware and block this number.
