Vodacom consultant argue with client

I have just received the most frustrating call from a consultant of Vodacom (I did not even get her name). I did my last upgrade in August 2020 on a top-up contract on which I receive 2.65gig of data, 200 minutes & 200 sms per month. The consultant tells me Vodacom is discontinuing all the type of contracts I am on and I have to move to the RED top-up contract. She explained I will receive 200 minutes and 2 gig daytime and 2 gig night time data for R110 MORE per month. I say no I do not want it as I will not pay more for a contract which I singed for 24 months!!!! She is adamant that Vodacom is moving over to the RED contracts. I keep on telling her I DO NOT WANT TO MOVE OVER AND PAY MORE FOR MY CONTRACT. She's still adamint and tells me I have to move over. I tell her I get 2.6 gig data at the moment and this is more than she is offering me. She tells me I will save in the long rung as I will recharge much less. I tell her 4 times I NEVER RECHARGE as I have Wifi at work and at home. I ask to speak to her supervisor but she just ignores me. I never recharge airtime as what I am receiving is enough. Now she wants me to pay more for my contract and receive LESS??????????????? She keeps on arguing with me. I get so frustrated because this woman does not understand that I will not agree to change my package as I will get less for more money. At this point I am so frustrated I drop the call.

How can a Company with which you have signed a contract for 24 months DEMAND from you to change your package to pay more and get less?????

I do not want an answer from a consultant I want an answer from top management, as this is a breach in contract.
