VODACOM FAILURE

Originating from helping someone whom lost their phone.... I assisted to buy a sim and rica the sim on my name. I am a proud MTN and CellC client, not having one day of doubt of making the write choice in service provider. I have discovered that this person whom I have helped are an ************* person operating on my identity. I want to cancel this sim card ricaed on my name. I have gone to Vodacom Cape Gate and the lady there said that they are unable to assist me and I have to phone Vodacom Customer Care at 082135. And so I did... Only to realise that the voice prompts do not accommodate or cater for my request. So I have tried a view different prompts but unsuccessful. Then I phone the branch again... VODACOM CAPE GATE and speak to LINDA, whom is an african female who tells me that I can not phone to Vodacom from another service provider and that I must phone from a Vodacom number to cancel the sim/rica. Then I said that it is ridiculous, she claimed I sweared at her and she cannot assist me an she cant answer my question in anyway at this time. When I asked to speak to someone else, the phone was put on the desk to run up my cellphone bill in waisting my money. Is this the pathetic people you nowadays employ that is untrained and spitefool/unproffessional. Point proven why I dont want anything to do with a service provide who CANT DELIVER A SERVICE!!!!!
