No response on contract cancellation

Hi<br> <br> I'm writing with regards to my request made via phonecall on 16 May 2015 requesting that my contract ***) be cancelled and my account moved over to prepaid. My reference number for the call is ***. The agent I spoke to told me that I would receive an SMS notification by the 26 May 2015 confirming this change and I was not to upload any airtime or data before I receive this notification. Today is the 27 May 2015 and I still have not received any notification of this change being made. Instead, as per normal MTN has credited my account with airtime, data and SMS bundles, which I refuse to use or pay for. As far as I am concerned I should not be getting anything esle from them other than notification that my account has been closed and I am moved to prepaid. Further to that, I did a check on my credit profile with TransUnion and found that MTN has not updated my payment made in April. Please will you ensure that this is done. I request that my query be attended to as I would like to carry on using my phone as normal.
