Vodacom totally unfair

I took out a contract for Wifi with a router in 2022 while my son was studying in Hatfield. He finished his studies in November 2023 and subsequently got married and moved to Noordheuwel in Krugersdorp December 2023. After logging a query stating that there’s either bad or no signal in that area I was told that there’s nothing that can be done. When asked if they could cancel my contract I was told NO. I asked to migrate the contract to fibre, that can’t be done either. I don’t mind paying for something that does work but to pay for something that doesn’t work, to no fault of mine, is just not fair and ridiculous. I have 10, yes 10 contracts with Vodacom and have been with them for 27 years. I have NEVER cancelled a contract and been paying by debit order. I was also told, what it boils down too, that when a contract is taken out that you can’t move for the duration of the contract due to signal issues. Who does Vodacom think they are???!!!! Krugersdorp isn’t on a farm or far from towers. So why is there no signal???!!!! I will take my contracts one by one to another service provider as soon as they expire.
