Overcharged Bill - Autopage

I logged a query in mid-July 2015 on my monthly bill for the data usage on my Ipad & was supp**** with a ref number with a promise of feedback 2 weeks later. I didn't receive feedback until I called Autopage customer service department on 11 Aug 2015. I use my Ipad for private & not business purpose & had always been billed in the range of R1000. My bill increased to 3 times and eventually 10 times what I had been paying i.e for May R3 333.99, June R5 612 and July R11 169. Kelvin Pillay was assisting & I requested an itemised billing but he instead sent me an invoice which had no itemised bill. I then requested that he transfer me to a Complaints dept at Altech but he insisted they had no such department & should rather speak to Accounts. In Accounts I spoke to Sandy who told me that my case had been closed and marked as resolved. She then suggested that I complete an online URL form to request my itemised bill as she couldn't assist in that regard. I am not happy with the service especially that no area could assist but rather shifted the problem to next people or dept. Can I please get this case resolved & be refunded whats due to me as I believe I've been overcharged.
