Cell contract to prepaid

For almost two months, I have been trying to get MTN to convert my contract which has run its course, to prepaid and for reasons known only to them, they continue to play delaying tactics.<br> Mid-December, I went into the Fourways Mall store to obtain a sim swap and was told then, I did not need to give a month's notice to convert to prepaid. On 16 Jan when I returned to the store to convert the number I was told my Ms Marumolwa that the information I was given in December was correct, but that they had received a mail late December, that customers now had to give a month's notice. Firstly how is that my problem, as I was acting on the information received in Dec. I duly completed the form and expected the conversion to be actioned immediately only to discover 2 February, that it had STILL not been done. I called the centre and was promptly informed to provide proof, which I duly did and that it would take 3 - 5 days for it to be excalated! And since then, I have not been able to reach any of them and have been told nothing, so as far as I know, I am still being billed on contract rates. And I have since hear of others with a similar problem with MTN. NCC my next step today!
