Search “cancel xm radio”

I cancelled my subscription to XM Radio a couple of years ago and it was such a hassle I shared my experience here. That post continues to generate comments and Google juice. First, the latest comment:

“Even though my credit card expired, they continue to send me bills. I have called numerous times to cancel but they refuse to do it. Instead, they continue to bill me through the mail and call relentlessly for the money. I am on hold now for at least 45 min. This is a problem that every XM subscriber should be aware of.”
How do these lost souls find there way to my obscure little post? Google search “cancel xm radio”

More than 10 million search results and the 2nd one (right after the company FAQ page) is a bunch of folks with horror stories about the company.
