Sirius XM has now called yesterday and today. I didn't answer and they left no messages. The caller ID dies say SIRIUSXM RADIO. I let my subscription lapse a couple of years ago but two days ago,I got a letter saying they were turning my SIRIUS XM back on for a few days for free. I don't listen to it and don't want it. They will continue to call, however. I am sure of that. If it gets to be a real bother, I will block the number.
