Not Upgrading - loose all other contracts discount

So I have three numbers/contracts with vodacom. So the one contract is a home wifi 066...2158and it ends on the 29 Nov 2024. So they say you must call a month early to say whether you upgrading or not. So I call today and tell them I don't want to upgrade on the 29 Nov 2024 is the end for this contract. The call centre agent tells that I will then loose all my other discounts on the other two contracts (066...0318 and 082...4763) that are expiring in June and Nov of 2025. My question and serious concern is how does one contract that is ending affecting other standalone contracts that are expiring later. So I am forced to continue with a contract I no longer need. It is expired and it must end. Now he tells me all discounts in all contracts that are still on and continuing will fall away. Vodacom what the hell??? So I call again and a different agent now. Now I want to know how much will it cost me to cancel everything because I now very angry. He tells me and then he asked me very politely why I want to cancel everything. He checks and tells me that is not true what the first agent told me. I am not sure who is telling the truth. Now I must wait to see my statement in 10 Dec to actually tell who spoke the right thing. However from this morning, I am so angry and disappointed on Vodacom. I have been with vodacom for 25 years. I have had contracts and cancelled contract before and non of this issues was ever said to me. That cancelling one contract or a contract that is not renewed will affect all other contracts with their discounts. So I am punished for not upgrading one contracts. Iyo....
