Keeps on increasing prices

I am extremely unhappy with the services currently being provided by Vodacom. This is in regard to your "annual price increases". In February 2025 I took out a new contract for home internet, speaking to an agent and signing the contract in store which stipulates that I will be paying R479,99 per month. Come my first debit order and I end up paying R528.22. That is a 10% increase, 6% more than the current inflation rate in South Africa. I was not aware of any price increases and nor was I told about any increases. If i had known i would be paying more than R500 a month, I would have opted for a different contract. I have already been in store to raise this concern where i was told to call customer care, after calling customer care, i was told to go in store again. This is utterly ridiculous and unacceptable. Now I am stuck in a 36 month contract, paying R50 more per month and I cannot cancel the contract without paying a penalty. This is costing me money and time unnecessarily.
