Inexcusable service of Telkom

My husband and I are the owners of Kaijaiki Country Inn, guest house and restaurant in Yzerfontein. We have a speed point machine and it is a shared line with Telkom. Since 28 January 2018, exactly NINE days ago, our telephone line was dead, meaning we could not use the phone, but most importantly, we could not put through credit cards. Not all clients carry cash with them. I had to ask them to trust us and had to write down all credit card details and their phone numbers for when the card machine was working again. We have phoned Telkom numerous time in this nine days, each time giving my name, address and phone number. Each of these times I told them that we are closed on a Thursday and there will be no entrance to the premises. One would think they made a note of this. Guess when the technician came? Yip, you guessed it! Last Thursday!!! Again we phoned, starting at step one. Today I saw the technician and told him to PLEASE come and fix our line. He checked and said it wasn't even on his system! He promised he would fix the fault before the end of the day. This didn't happen. My hands are cut off. People at the switchboard, upon calling 10210 also escalated the fault and various e mails were sent to the technicians. What now??? HELP PETER!
