607 358-7305 is SiriusXM attempting to get those who purchased a vehicle and have a trial version of SiriusXM about to expire to sign up for a subscription. They will keep calling and keep calling and keep calling until you address them.
The way I handled it was to call the number and connect to a live person and ripping them a new one. They couldn't get me to agree having Sirius in my new truck if they paid me to have it. Why? Every day for the past 13 days they have called and left no verbal message ... just dead silence. I feel their tactics are by far over the limit of my patience and I want nothing to do with them. If they left a message the FIRST time they called they may have got me to do business with them ... their loss.
