Bad in communication

I have always been a fan for Telkom, however one mishap where I missed a debit order but was able to pay it via EFT as they do not allow to pay in store but for some reason their system does not communicate, I paid the account on the 2nd of May to date I still get message that my lines will be disconnected due to unpaid balance for heaven sake I even have confirmation from them that the transaction was successful, I am on the line with them for over 20min what the hell, we are all hit by COVID-19 but we do make sure that the lines are mended better so I want to know if they suspend my lines who will be responsible for the loss of business that day and they threaten you with being blacklisted well I am reporting them to the consumer council as well since I did honor my agreement if their system is delayed not my fault,
