Bests & Worsts Reviews from Amazon

Got a card with an $8k limit in November. I hadn't received a statement as of mid-December, so made a note to look into it. A day or so later, I got a note saying payment was overdue and they'd cut my limit down to the few purchases I'd made at first. I made a payment and applied to have the limit raised back up, but they refused. I promptly close the card. How can you expect people to pay a card when you don't send statements!? I did get all subsequent statements, so they seem to know my address. An email with statement notification would have been nice too. They seem to know my email address when it was time to tell me I was overdue. This is bad faith dealing, pure and simple.
