I guess it’s not about the second alternative id, as it’s maybe allowed in stake(i have forgotten though).
Also if it’s not allowed in stake of multi account then at first he shouldn’t be assigned to his VIP host.
I guess there is some misunderstanding between both the parties.
And also we should not blame Steve for this, without listening or seeing the actual fact.
OP have you tried contacting Live Support at site and also if possible message here Stunna with your issue.
