Bad service

I went in to MTN Waterfront on the 26 March 2016 to cancel my contract Lauren was vey helpful and logged the migration request to prepaid for my number. Req#: ***<br> She told me that the call centre will contact me the next week to finalize the cancelation.<br> <br> Due to meetings I am not always able to answer my phone. I received 2 calls from a 083 number that week.<br> The first one I answered but nobody spoke. I could just hear the back round noise of an call centre and it then disconnected.<br> The second call I was on a meeting and could not answer my phone.<br> Today the 11 Apr 2016 the call centre phones me and tells me that I am due for an upgrade.<br> I told the lady that I had canceled my contract due to bad service after which she offers me another contract and tells me that my contract is not canceled cause I did not phone the 8080 number!<br> <br> When I told that I am not interested in a new contract she just said good bye with no other confirmation or assistance to cancel my contract.<br> <br> I will be canceling my debit order as the contract seems impossible to cancel!
