I tried something similar with a big bank once. I got calls from collections agencies about 9 months later. I ended up paying them about $50 in account fees to save a black mark on my credit report. They were charging me to keep my account open even though I made it very clear that I didn't want that, but I didn't go through all their proper paperwork.

So yeah, it's not like any of these types of establishments care at all about their reputation. They'll gladly ignore your not-to-their-letter cancellation, stop contacting you, and send your $50 usage fees for no actual usage to collections.
