Telkom Smartbroadband

I bought Smartbroadband data on 2 July; 20Gig + 20Gig Night surfer. On 6 July 4Gig; 7 July 2gig; 8 July 10gig. In a matter of week 20Gig data was depleted and also 20Gig night surfer not available. Logged call on 12 July, was not given an update. Received SMS 18 July case closed no unusual data depletion. the usage of data in one day is very high and not justified. I requested report and to date not received. on 22 July I went into Telkom store, the agent advised me that Telkom back office noted a comment, not to log another call for this problem. My problem has not been resolved, and I am very disturbed by service to assist.
