[Injera]

For now, should I continue trying to order on this account (if support replies and allows the purchase) or switch to another new one, or try my personal account?

If the account's Inconsistencies have been sorted out, you can go ahead with your SEs.

Will the record of my customer support chat for account verification be linked with my chat when I eventually EB customer support? Sorry if I'm asking a lot of questions/questions that are tough to answer
