Telkom Yet Again not Upholding its own Contractual Description

We purchased the 12th deal of Christmas on the 23rd December 2017 and was helped by Mbuso at the branch in Canal Walk where we were told that the package agreed upon was that only R149.00 would be deducted monthly. The package contained 100 minutes, 1 gig data, 50 free sms's, 2 gig data for IM and Whats App data. The 1st five months we would receive 10 gig data. Yesterday we were debited R 225.00. Why Is it that it that Telkom is allowed for A debit to taken which we have not signed. When I called in to the call centre and spoke to a manager by the name of Sibusiso I was told that I was using out of bundle data. I kept saying that we never reached the limit and was told we used up the all network data and not the the telkom data but was due to coverage issues. He then kept sarcastically telling me that the consultant at the branch never explained the spend limit option to properly. Why is it that we the clients then have to simply litteraly pay for someone else who does not explain these things upon application. Its rather frustrating that we are just entitled to accept this manner of service and poor lack of product explanation. It in serious breach of the Consumer Protection Act as we are being mislead. We gave also not received a single bill for this account since we app**** for it in December last year. How is that possible
