Lack of proper customer service and foul play in Data usage

1. I am very dissatisfied firstly with the level of service i received from a customer agent i received last night 28/08 when I was enquiring about data usage and contract upgrade, I had asked her to escalate the matter to her line supervisor. manager and CC me on the mail so that I can know that Telkom is doing with the issue. 2. I am extremely dissapointed with Telkom and the unfair manner that relates to data usage. with my previous plan i received 5 Gig data monthly and generally I had used that data until round about the 15th of the month, Yesterday my upgrade package was activated where I received Pro rata data of 6Gig (The package is 20Gig day and night surfer), the very same day the data depleted and I believe there is foul play from Telkom, throughout my previous package I have never utilised that 5 Gig in one day, and I believe that there must be something wrong on your side, When I called in another representative this afternoon 29/08 that they cannot give me specific data usage report where I can see what has taken up my data. Telkom if this is how you operate with data then I'm going to have to reconsider my contract because it is not yet 7 working days since I have received my package.
