Worst service ever

My account has been suspended for no reason. I paid my account 22MAR18 that was due 05APR18. This morning I had no internet & no landline. Been online with Telkom for the last 3 hours, being send from pilar to post and still no landline. 1st spoke to Technical department, no need to speak to Billing - spoke to them - no need to speak to technical - spoke to them - no need to speak to billing. After 3 hours a fault has been logged and I have to wait 48hours. I am running a business from home and cannot wait 48hours for my clients to get hold of me. This is unacceptable - I can understand if my payment was in arrears - but I paid in advance.
