VERY BAD SERVICE

I have had it with Autopage. Like I said in my previous comments they deducted R1361.89 30/04 from my account after I agreed to have a pre-paid account of R490 - which includes 100 minutes talk time, 200 sms and 300mb data. PRE-PAID, TOP-UP??? what is so difficult to understand. I posted a complaint on this website and they phone to say the best they can do is to credit my autopage account with R500 for their mistake. They assured me my contract was now on a pre-paid and promised that no further costs will be deducted other than my pre-paid amount of R490. They would credit my account with R500 so I'll have R10 credit. However 29/05 they deducted R1887.79 from my account. I have not heard or seen any money paid back. I received a mail saying they will attend to my request. I received a sms saying my account will be credited but NOTHING has happened. Today I phoned them and they were not aware of the fault??? Now I have to wait 7 days before someone will attend to my problem. I WANT THE MONEY BACK IN MY ACCOUNT. NO CREDIT'S I WANT THE MONEY IN MY BANK ACCOUNT. I want to close my contract. This is ******** and I'm sure I have a strong case to take to a Lawyer.
