Paying for a ********** Vodacom contract

In October'18 I was contacted by Vishnu Chetty from Vodacom and told because I have been a loyal customer I qualify for a free laptop and rooter with NO EXTRA charge, all I have to do is extend my current cellphone contract with a year. In other words my current contract will now be 3 years and I can only upgrade my phone in 3 years not 2. He has now **********ly opened a new contract under my name with a new number that I now pay for and never agreed too. I never received a new contract, I never signed for a new contract and I never received a new sim card. I have been trying to resolve this matter but was told by Ashton I now have to go to a Vodacom store (I live 3 hours away from the closest city) to be able to listen to the recording with a agent. I have been paying for this contract without knowing I had it. This is ridiculous! I was **** to by Vishnu Chetty and Vodacom and no one seems to be willing or able to assist me. Pathetic and disgusting from a multi billion rand company.
