Is it your first order?
If you still have pending payments due from your first Tamara order, you may be unable to place another order with Tamara until payments for your first order are complete.
If this is not your first Tamara order, you should be able to place a new Tamara order even with pending payments.
Do you have overdue payments?
If you have overdue payments, you will not be able to place another Tamara order until your overdue payments are complete.
