Stamps.com = rotten

I have sent Stamps.com a number of requests to cancel. I've been on hold with their customer service "cancel" phone extension for countless number of minutes waiting for a human to speak to. My inbox continues to fill up with messages from them, even after numerous replies to cancel. My time wasted with this vendor is disgusting.

Out of all the web services I've used, Stamps.com has the very worst customer support (if you want to cancel).
