Same here.. Paid $59 for it, paid for 1 month, and luckily my debit card had expired, because they make you go through a large hassle to unsubscribe to PSU. You can't do it on the xbox, and you can't email them.. I emailed them about 10 times and told them to fuck themselves.
Even after that, they kept my account online for like 4 or 5 more months, and I think they just finally turned it off last month. They can kiss my ass if they think I'm going to pay for those 4-5 months, with less than a week played.
microsoft may be big and bad, but they don't have their shit well organized. I consider this how AOL used to do.. They'd offer a free month, ONLY when you put in a credit card, and then they wouldn't automatically stop the subscription, and there was no way to do it online. So, you had to call some indian or pakistani fuck-knot that couldn't speak a lick of English and go a couple of rounds and hope to get the job done within two or three phone calls, 2 1/2 hours of precious time, and a 1.75L of some cheap over the fucking counter rotgut blended whiskey.
OK, maybe I overexaggerated a bit there, but not by much :/
