MTN is not doing the cancellations on time

On 23rd December 2015 I phoned in and cancelled my contract that reached maturity. Asking for the number to be migrated to pay as you go.<br> <br> Now I get a bill that I need to pay in February which is RIDICULOUS and still my number is on contract!<br> <br> How F***up is that!<br> <br> Well I would love to see how you guys get that money! <br> <br> Fix this, I paid my last amount to you last month! I owe MTN nothing!<br> <br> The retentions department is really pathetic!<br> <br> How many more times MUST I phone IN!!!
