1OGB Data dissappears and Telkom cannot give me answers

I am so frustrated with Telkom, Last week they sold me a wifi package for R269.90 a month for 20GB. I shouldve received prorata data which no one at Telkom can tell me how much I received. Two days later the data showed depleted and I bought an additional 10gb, 2 days later thats finished as well. The problem is I have been using 10GB of data before on Telkom mobile and it lasted 1month and some days now how can 10GB of this new Wifi finish in two days being used for the same thing? Telkom call centre manager MUSA says Telkom cant give me a breakdown of what happened to my Data and I should call ICASA. Why am I paying telkom if they cant tell me whats happening to my data. I am so frustrated. Basically Telkom should be able to check whats going in. Yesterday I was offline for 30mins, on phones and internet just because Telkom ca!!!! What are we paying for?
