Telkom Suspension of account yet I have fully paid!!!

My debit order goes off on the 25th of each month, I get a Telkom message confirming my payment only on the 4th of May and on the 5th of May another sms saying my account is suspended for non payment. I am furious as this has cost me to put data on another sim card, I have no wifi and no contract cellphone use, I get told it's a 3rd party issue. This is outrageous and unacceptable. I went to a Telkom store and get told because it's Friday afternoon there's no one they can phone to reactivate my account. While I was there another inconvenienced customer had the same problem. I must suffer for no fault of mine and spend extra money to have internet usage. Disgusting service 😒
