Cancellation of contract

I've sent in my cancellation form the 24th of February 2016 to cancel my cellphone contract the 29th of March 2016, because then the contract is 2yrs old. It's now the 3rd of April 2016 and still the contract is not canceled!! I will not pay telkom another cent for their bad service!! Also I will not recommend a single soul to use telkoms service. When I went in store the lady couldn't do anything for me, she says telkom customer care has to phone me first. How long can that take??? I've being phoning telkom everyday and they can't do anything, they say telkom has to phone me first to make sure I want to cancel my contract. I'm not gonna change my mind I want to get rid of Telkom!!! I will not pay another cent for the service I'm getting now, because I didn't ask for it!! I will not ask for a refund if they're gonna take money this month because I don't want they're service anymore!!! Also the lady gave me another cancelation form to fill in?? Why?? Im not gonna waste my time with them anymore I'm sick of telkom and their bad service!!!!! See my billing account number, maybe someone can give me some feedback <br> <br> Thanks!
