No service

I called on Monday (4/4/2016) to end my 2 data contracts. A lady helped me with the quotations and I paid the amounts due. That was e-mailed to ***,za with an ID copy. I enquired later in the week and was promised by two people that the conversion to pre-paid will be finalized by 8/4/2016. It was not done. I had to call various times to follow up with nobody helping me. This morning (11/4/2016) I called and the voice said that I have reach my limit of calls to the call centre and can only call again in one month's time! I had to call from another phone just to get put through. The person could not tell why it has not been done, told me to send an e-mail (to which nobody replies). I asked to talk to somebody but he said the people who do the cancellations does not have phones. I could also not speak to his manager, he said he will give him the details. <br> Please help!!!
