Vodacom increase ridicolous!!!!!!!!!!! 8% in a country where inflation is approx 3%???

1) I need Vodacom to please explain how a contract that was signed end November 2025, is already up for an increase in March 2026?

2) Surely the contract price should be fixed for the 2 years of the contract?

3) The inflation rate for 2025 was at an average of just over 3% yet the Vodacom increase is over 8%????

No additional benefits added for this steep increase?
