Telkom does it again

I have an account with telkom for data and voice. They offered me double my data for the next 6 months or so. Only to realise half way through the month I couldnt connect to the Internet. Logged several calls and received smses saying it had been fixed which it never was fixed. So for 2 weeks I have gone qithout internet. Then trying to call my landline number its now telling me the number does not exist. Like really? Its not like I am owing anything on this account. This is bull. Calling yhe call centre all they tell u is the issue is with our Technicians who i oressume dont give a damn about if its fixed or not. They pretend to have worked on an issue just to get brownie points from their bosses.
