ALMOST IMPOSSIBLE TO CANCEL - BE V CAREFUL

I took out their LTE offering - and although the speed was great, my data usage was unbelievably high - impossible really. So I cancelled within the first few days - last December 2014, but I am still being billed by Telkom ( their provider ) and am still trying to get them to accept that the contract should be cancelled. I returned the equipment to Telkom. It is an unbelievably frustrating process - I urge anyone to be VERY VERY CAREFUL WHEN GIVING THEM YOUR BANK DETAILS - maybe rather go with a company where you can get some intelligent response. It took months to get Blue-Tech to acknowledge that I had validly cancelled, and it is still taking months for Telkom Retentions to cancel. Yet they still ask me the same questions every time one of their retentions agents phones me. Today, when they called, I told the woman that I could not hear what she was saying, could she please call me back. Her reply, \ Well I can hear you : and she put the phone down."
