I want my data and WiFi back

I remember taking a contract with Telkom a few years ago when I took up a 7' tablet. There was this guy there that always helped when I needed help. But he didn't last long, I hope he was promoted to management or something. I remember I referred alot of clients to Telkom because of that guy. Then I took up two more contracts with Telkom, a cellphone and WiFi router respectively. Everything was ok, I say ok because Telkom has terrible service. When you call them for help you are lucky if you get someone who is willing to help and and actually not rude at all. In August I Telkoms network was completely down. On the 4th I think they gave everyone affected 1gig for a 2 day period. Mind you every month I get 1 gig on. My mobile and 15gig on the router. Which for the past 22 months, I have not been able to use up. Now suddenly my data and WiFi is depleted by the 8th of the month. This happed in August and again now in September. The strange thing is I have been doing the same thing I have been doing the last 22 months.but my data, WiFi or wattsapp data was never depleted. When I enquired, they gave me some stupid story about my applications being left open, which is nonsense. I bought a add-on gig and that also didn't last. Telkom is busy with something dodgey. I want my data and WiFi back. What on earth am I doing with data or WiFi when your network is so pathetic it's a wonder I can even log on to this site right now. You are *****ing my data and I will not sit back and let you carry on robbing me. You can never get help when you go to the branch, they send you to the call centre and the call centre is useless. The only thing Telkom knows is to send you emails for SMSes to rate their servise. The worst network provider in Africa.
