Contacted about a ban from the old Pirox days. Very professional looking letters. However I probably did damage by filing a couple tickets years ago. Not really expecting to get the account back due to the mountain of evidence Blizzard has, but figured it was worth a final try.
1st ticket: Cancelled
2nd ticket: Deleted
3rd ticket: Cancelled
4th ticket: Deleted
5th ticket: Cancelled
6th ticket: Cancelled
7th ticket: Cancelled
8th ticket: Cancelled
9th: ticket: Cancelled
Edit: After 15+ letters, I eventually gave up. Tickets were just flat out ignored at this point.
