What does it take to cancel the Damn exp. Contract

I had a contract for Data with Mweb which expired last year around this time, called a month before expiry date to cancel the contract but I was given some incorrect login details to login to their system and cancel the contract, couple of months later I called again because the debt order was still going through and I was given incorrect login details again, I called again a month later and I was told that the contract will be cancelled which was not cause the debit order still goes through.<br> <br> I have been overseas for a year now and I'm not even using their SIM card and I don't understand what it takes for them to cancel this contract.<br> <br> I'm tired of calling and being put on hold for more than 20minutes using international rates
