How did you make the payment?
Different methods take different time to be updated in their system. The fastest would be via JomPAY.
However, for your case, have you restarted your phone? Sometimes it need to refresh the network first after they un-suspend your account.
If that fails, I would recommend you to e-mail them your payment receipt and then contact them via Live Chat to check it out.
