calls twice a day, once in the moring and then at night, leaves no message.I called back and It says it is for Sirius radio. I spoke with a man with very bad broken English who asked me for my phone number, address etc. When I asked him to verify what he has in front of him he said he does not have that information!!! WHY ASK ME FOR MINE IF YOU CAN'T SEE IT ON YOUR SCREEN? I feel this could be a scam!!
