Telkom billed me for service not received.

Hi

I app**** for telkom home fibre where I have submitted all documents required as requested.

And I was told that the technician will come to do the connection at my home. After a long wait the technician never came . I even went to telkom shop to query. But their technician never came. To my surprise last month I received a bill though the technician never came to connect the fibre. I called Telkom they told me that they cancelled the bill as I have not received their service. Today again I have received Telkom's bill it included last month bill.

I no longer need their service can they please rectify their billing system as I don't owe them anything
