Vodacom upgrades

I recently received a call from a company that does upgrades for vodacom the lady was upgrading me to a home internet but did not tell me and did not tell me if ot is home internet i wont be able to use my phone . The sim card wont work in my fone beacuse it was upgraded to home internet . I. Called Vodacom and trying to to reverse the contract I eventually got the contract reversed but they told me the reversal will only happen in the beginning of the next so im going to have to pay for data that i cant use on my and i can use my phone its say no servise because this sim card can only be used in a home router. Every second year when i must upgrade im having problem with vodacom. This will be the last . i will be cancelling my contracts with vodacom.
