****ed by Telkom

I had 3 contracts with Telkom and 2 were due by August and September I went to the store to cancel them and I was told that I need to call their customer care to cancel which I did but they still billing me even though I asked to cancel. And their consultant told me that the 2 contract have been cancelled. Now I'm being told that I never cancelled my contracts and what is surprising is that we are always told that their calls are recorded so how come they don't have my cancellation?
