Disgusted Telkom customer

I'm totally disgusted with the services from Telkom. I have been trying to cancel my existing mobile contract with Telkom for the past month without success. I have been to the Telkom offices in Cresta and was told to cancel it online. I have tried several times to do so with the following message " We will contact you to confirm your Request". I have not received any correspondences to date. I then called the call centre to cancel and was told that I can only do it online. I approached the customer services and was advised that my query will be escalated. I still have not received any response. I will not recommend Telkom to anyone. Their services is really appalling.
