Not taking no for an answer

I was phoned and informed that I as a good customer qualified for a Vodacom Smart Tab 3G. The caller said he was from head office. I said that I am not interested, and he stated that I could use my old sim card and that it will not cost me anything. They sent me the device with a courier and I asked for it to be collected as I did not want it. I was ignored and they still did not come and fetched it until this day. I have sent letters for it to be cancelled and I visited my nearest branch in Piet Retief where the consultants have called twice already for this contract to be cancelled but it is still being ignored, and they are deducting this amount every month, I am a pensioner and I can not afford this contract. It is unbelievable how they can keep on calling everyday to sell you something but when you need to talk to them they are nowhere to be found. I am sick and tired of this service!!! <br>
