Hello trinity, if you have as of yet not sent in an rt you may find this useful. Check out the paragraph in bold
Having trouble resetting password
What I would suggest to save possibly some time is in your initial rt in which you should include a new alternative email, try to give as much info as you can remember such as igns whether you bought ap with the account or not including any transactions if you still have a note, rough time you remember being on account and anything else you can think of in first communication.
If it is not enough they will of course send you more questions to be answered.
