Not really sure about that. I think I have only forgotten about maybe one or two and they were on a like 6+ month renewal and when I saw it I canceled it immediately and filed a claim for a refund.
One of them tried to screw with me until I told their rep that I was willing to spend more on a Lawyer than their shitty subscription that used dark patterns to keep you from being able to cancel. They refunded me.
Sounds like you were trying to cancel Sirius XM lol
Actually, I canceled Sirius and had no issues. Though, that was a VERY long time ago. I bet its a real PITA today though.
I've had it a few times. First time was 2006 when Howard Stern first moved over. Took over a month to cancel when I realized I never listened to anything and his show wasn't good anymore. Then I got it again in 2010 when Radio Shack has a sale on the equipment. Same thing as last time: took about a month of fighting them because they kept saying a manager or someone else would call me back from the cancelation department.
Last time was when I got my Subaru and it came with a free 3 months. They actually sent me to collections rather than just turning off the service because I refused to give them a card. That was a massive pain and I had to threaten legal action before they dropped the charges.
Never again.
