Incorrect contract

Helopeter! I have a problem with vodacom. In November during Black Friday there was a promotion of 250G for R250 online. I asked for more information and the consultant called me to explain. I specifically asked for sim only data ....that the data must be sent to my vodacom number because I hate using a router,I have difficulties connecting to it when I am in the rurals plus the continious charging and I had data sent to my number before instead he gave he a home internet and took the number that I use for my calls, my insurances,everything and to be used a ms a router number. A day later my number was not working I called vodacom and asked for an error to be corrected but nobody cared to. They said they can cancel that home internet bring back my number and I re-apply for sim only data but they didn't cancel it but they ended up telling that they cannot help me now it's post 14 days yet they were the ones who kept giving me 24 to 72 hours for them to fix it.Till today I'm paying for the data that I am not even using. Is that fair? Please help me!!😌
