I took advantage of an offer for three months for $2 (total). I didn't think about it at the time but this is their way of getting your credit card number, which is set to automatically renew at the $29 per month rate. I tried calling to cancel and got the run around (not being listened to, put on hold for several minutes, transferred around, told I couldn't be heard, hung up on). SiriusXM is the probably the worst business I've ever had to deal with when trying to cancel. I really feel like they run a scam. I finally got through using their chat but I don't trust them and I'm going to alert my bank that I cancelled and that no further charges should be honored. We'll see.
