PAYING FOR A SERVICE WHICH I AM NOT GETTING - PLEASE CANCEL CONTRACT!!!

Good day (THIS IS PROBABLY THE 8TH HELLO PETER COMPLAINT) I am really frustrated. Telkom went and debited my account again. I lost 4G of data, because I cannot use my Telkom internet. The download speed is 0.79 Mbps and the Upload speed is 0.19 Mbps. It is basically non-functioning. Please can you cancel my contract so that I can go somewhere else that I actually get what I pay for. Thank you Lisa
