Soft Lock removed from contract, Over billing,

I am a customer of Auotopage (AP) for many years with 4 x contracts. I have had a contract for my son which was soft locked for years to prevent over spending. Every moth the account was spot on and when limits were reached we have the option to top up. This the trend for years, I actually stop looking at the billing, until about 4 months ago we received bills for just under R1000 and one over R1000 and for May 2015 one for just under R 2000. When spoken to different branches, the buck just kept on passing on. All back to Cape Cate AP where the contract was upgraded last. Cape Gate AP seems also not have a clue on what to do and logged a billing call, where AP Head Office will assess the issue, rectify the problem and refund the excess monthly overbilling to my account. They should have get back to me in 48 hours and it is now a week since. What is going on AUTOPAGE??? <br> Two contracts have reached their end and I will definitely not go back to AUTOPAGE. Seems now that they plan to CLOSE SHOP THEY DO NOT CARE about their customers any longer.
