Telkom's disappearing data

We have been having problems with the Telkom Wii for more than 3 months now. We have only been getting half of the WiFi we are paying for, so we are forced to buy extra top-ups as we have work to do. We have also noticed that the connection quality has decreased drastically from the time we bought it.

We have been sending emails with screenshots attached to the Telkom complaints department since September with no reply to date.

It is absolutely shocking how we are being ********** and no one even bothers to help us. We have brought this matter to attention 2 months ago and they do not even bother to respond to us.
