Suspended line - No answer to calls or emails

My account with two lines was suspended yesterday for non-payment. I have a debit order going through for payment so I do not know why the debit order did not go through. Anyway I cannot get hold of anyone at the call center as it has been 'closed'. Nobody responds to emails or queries made through the Mtn website. I don't know what to do. I emailed my proof of payment to customer care. I have received no response and I don't know when my lines will be active again.<br> Please assist urgently.<br> Thanks.
