I DO NOT HAVE A TELKOM ACCOUNT/PRODUCT BUT MONEY IS DEDUCTED AND THEY ARE CALLING ME

Money has been deducted from my account by Telkom, my bank has managed to reverse 2 transactions done by Telkom. This week, I have received 2 calls from Telkom, telling me that they are at Stonehill Office Park (I don't know where that is), to fix a data line in my office. I told the first caller on Tuesday that I am not a Telkom client or have an account with them, I thought that was understood and then today in the morning I received a call from another person telling me that they are at the same place (Stonehill Office Park) to fix my data line. Can Telkom please delete my details on their records because I do not have any services/products that I am using from Telkom.
