I hear you, it's a complicated problem with many sides to it (I was also involved with call centres from the software side). In my particular case, I was just disappointed with everything from the implementation of the actual free trial, their silent changes to my billing details, adding penalty fees when it was clearly their mistake, daring to deny me access during a month I'd already paid for, completely indifferent call centre agents, and lack of any response from their management when I pointed out the original problem to them (multiple times). And this was a small company who supposedly pride themselves on service - I suspect they've grown in size sufficiently to be flooded with support calls now.
