Telkom worst service in my life -Incorrect wifi package allocated

In 24 July 2017, Telkom had a promotion for 20gig day and 20 gig night data for R299. I phoned the call centre and app**** for the package. What a shock when I got my first statement: I was allocated a 100gig day and 100gig night data at R 1049.00 per month. Needles to say I was extremely upset as that was not what I could afford. Since August 2017, I have called Telkom at least once a week and also liased via e-mail. Every time I had to repeat the same story even though everything was captured on the system. I also complained in-store. It was confirmed by the supervisor, who listened to the call, that the incorrect package was allocated to me.Till today, no one had done the decent thing to return my calls or e-mails with an apology or to rectify the matter. Every month the money is deducted from my account and leaves me in a bad financial situation. I contact them every week however still no resolution...
