Call the credit card company and dispute the charges. Also, block any further charges if you can. Nothing gets people's attention like messing with their cash flow.
The downside is that the account will likely never be opened back up if a charge is disputed, and any future accounts could also be linked and auto-closed. Of course, if it's been closed for two weeks already, that's likely a moot point.
To be honest, the same issue happens on desktop browsers, it's just not as noticeable because the default zoom kinda matches what you'd expect. But you can still scroll to the side, in a desktop browser. See:
However, different browsers behave differently™, so you may need to also add:
word-wrap: break-word;
white-space: pre-wrap;
To make it work in Firefox (but you might need to adjust other things, also play with word-break CSS property, and test in all browsers). I've dealt with this previously at https://github.com/shurcooL/play/issues/4 and other places that deal with displaying user generated content.
