Reactivate Deleted Acoount

This ID "*** Email address is removed for privacy ***" was deleted by accident (actually a Tech support guy named Saranish at *** Email address is removed for privacy *** told me to do it). He assumed that I could change my "Primary Alias" in a "live" account that I don't use into the correct name (*** Email address is removed for privacy ***). Every time I did this The message that appeared  was that then account name "was not available". This occurred even after another Tech support guy told me to wait 30 days before attempting to reactivate my correct account name.  I am still unsuccessful doing this and it is imperative for business purposes that the correct account name is reactivated.   I need help reactivating the correct account name "*** Email address is removed for privacy ***".
