Vodacom makes me RED of anger

I have a cellphone contract which is almost 3 years old, I was on a package that suits my budget for all this time. About 2 weeks an agent called me to revise my package I clearly said I don't want to pay MORE so no thank you!!! He then told me I am actually going to pay less than what I'm currently paying only find that my new package is now almost R200 a month more. Can the consultant not do maths or are you just blatantly robbing customers?? I do not use the data I want my package changed to what it was ASAP
