MTN makes it difficult to cancel a contract

Good day<br> <br> I am trying to cancel my daughter;s MTN contract ***. the expiry date is 22 April 2016.<br> <br> 1. Canal Walk said to me in March that I can only cancel in April<br> 2. St Georges Street Branch close to Thibault Square said to me yesterday that they can not help me cancel it and I need to phone 808 to cancel (?)<br> 3. Phoned 808 today. The person helping me was very friendly but I do not understand the process.(?)(<br> <br> a) He said that I had to cancel 30 days before expiry and therefore I will still be invoiced on 01 May 2016.<br> b) They will cancel in 5 to 6 days but all the remaining airtime data will be wiped then.<br> c) I must phone agaiin on 23 April to cancel since the contract only expires on 22 April 12016 (???)<br> <br> Please help me to cancel this as soon as possible. I want to keep the number and the airtime still on it.<br> <br> Many thanks<br> <br> Mariet ***
