Where is my BIS and pay as you go

In February i called the call centre to enquire why after my change over from pay as you go to contract, i was unable to use my BIS. I was told that my name would be put on a spreadsheet and it would take about 15 days for my BIS to reactivated. I also explained that i had just purchased BIS services and now it has been deactivated. R59 lost just like that. The 15 days passed and turned to 30 days. I called again and again i was told about a spreadsheet and out of frustration i wanted to know what procedure to follow if i didn't want the contract anymore. I was told to pay over R800 to cancel the contract. The contract terms is for R35 airtime for R40 or something like that. I just want my BIS back and my pay as you go terms. Your service stinks and you should work on your customer care. No follow up and no feedback. Give me my BIS back and my pay as you go.
