I am writing up an email to send to there right now. It's currently in rough draft status. Does anyone have any suggestions of what to put in there to guarantee (as much as possible) success. If anyone has been successful, what did you put in there?

So far I've written in about how I signed up for unlimited internet, so thought I had unlimited (surprisingly enough) and after investigating I have found out that these charges are being introduced and people are cancelling under the 10 percent rule blah blah blah.

So- any more to put in there?
