Vodacom REFUSES to cancel my contract!!!

I have been trying to cancel my contract for one month now and until yesterday they delayed it and delayed and delayed it.... <br> <br> I spoke to Mpho yesterday who assured me that the contract will be cancelled and transferred to prepaid as of yesterday. Today I get an SMS to say my recurring data bundle contract has been changed to a recurring data bundle contract??!! That is not the instruction I gave Vodacom!<br> <br> JUST CANCEL MY CONTRACT AS INSTRUCTED and stop pushing me around!!<br> <br>
