Overcharged for the third time in 2 months

On the morning of 26 September i purchased a data bundle of 250MB @R59. By the morning of 27 September 2015 it had still not been activated yet the charge of R59 was added to my monthly bill. I called the contact centre and was told by an idiot that it was surprising that that would happen and he didn't know how to assist me. I then called 082155 and was told that the data system was offline and i would be called back, to date still no data activated and no call back either. I see now that i am being billed an out of bundle rate for data usage. I want two things to happen: Firsly i want the out of bundle data charge since the morning of 24 September until now reversed and i want the monthly recurring data bundle purchased cancelled as i did not receive the data balance and the R59 subtracted from my monthly bill before the 03/10/2015.. This is the third time in 2 months that i am being overcharged by Vodacom. Totally disgusting to say the least!!!
