Telkom Internet speed most pathetic, avoid at all costs.

We decided to enter into an agreement with Telkom and signed up for 10MB per second uncapped Wifi. We are on an ADSL line in Brenton on Sea and since inception and installation, we have never had the speed of 10 MBPS as undertaken to provide by Telkom. The speed has never been higher than 8.4 MBPS and during peak times it is as low as 3 MBPS. Impossible for streaming and we are not receiving what we are paying for punctually every month. Buffering is the worst experience ever when you try and stream anything on your TV. Simply pathetic. Bottom line, avoid Telkom ADSL Wifi at all costs because they are unable to deliver. After spending hours and hours on the phone with Telkom complaining about their breach of contract, nothing is being done about it and Telkom's attitude is simply that the speed is what it is and that we must live with it. We shall be cancelling our contract and if anybody can suggest a proper service to make use off in Brenton on Sea, please advise me accordingly. We apparently must have at least 10 MBPD speed uncapped Internet to stream properly.
