in the beginning of may i app**** for telkom unlimited free me with unlimited data. the first month i queried why i only got 25g she said its only pro rata data next month will be unlimited next month cam 25g the internet dont get slower its non exsitent no the consultant then only tells me on the unlimited data i only get 25g. so i went to their welkom branch asked regarding the unlimited free me where they tell me it's only after 100g then it will get slower. i feel if the lady informed me correctly the first time i queried it i would have cancelled then and npt have to pay for june. now they want me to pay the full amount for june although i cancelled on the 10th of june and the sim was disconnected so why should i pay for something i was wrongfully advised about even the pamphlet says unlimited data. i even phoned twice their sales nr to get proof i have recordings where both of them advises me on the unlimited data their is no capping and the internet will not get slower. i only took the contract for the unlimited data so if i was advised correctly i would not have taken that contract even the sales guy at their welkom branch says they cant say unlimited and only give me 25g. its either unlimited or not. so now they want me to pay r1900 + r800 for cancelation because i cant change the package. if they advised me correctly and said on the advertisment only 25g i would not have taken this
