I WANT TO MIGRATE - YOU HAVE TO LET ME GO!!

my one contract expired on 30 October. i was advised to call on that specific day and request a migration to prepaid. which i did. i was told on that day that it would take 5 to 7 days. the 3rd week in november i called and found that the migration never happened. the person i spoke to, ensured me that it would be done, this time within 2 hours. today, 30 november, i've found it was not done. i spoke to Ismail Kamwendo, who told me that they have \provisionally"extended my contract for another month. are you kidding me? i've told the first consultant that i was not using the sim anymore. i didn't even bother to do a sim swop. yet i've paid. now you've provisionally given me \""nothing\"" and yet i have to pay for that!!! why???!!!! why on earth is it easy to get a contract and so difficult to cancel it?? i need someone to sort out this mess immediately. and kindly note"
