Contract Cancelled and no response of how to fix

I called in to the cancellations department to get a quote on cancelling my contract. During the call, my line was cut. I rebooted my phone and had signal again, so I called back to get the quote. I was told by Mkululego that my account is on prepaid, i.e. my contract has been cancelled. He then proceeded to tell me that since it is cancelled, it is likely that the cancellation amount of R1713.02 will be debited from my account when my debit order goes through. 1st of all I did not agree to pay that amount as I only asked for a quote. 2nd of all, that amount does not seem correct to me, I phoned in to get a cancellation quote in February and the amount was R1886.96. The 1st quote from Feb showed the breakdown of device and airtime costs multip**** by 4 months (the remaining number of months on my contract). However I I still had not received the new quote, which have been for 3 months remaining. So I phoned back the next day and spoke to Makhosi, he sent the quote, which arrived only at midnight. Rt shows my airtime remaining was was R200 X 0, but they show that it equals to R800, which the same amount that was due in the last month. I have tried to call back to clarify but no help
