Unreasonable Price Increases

I have a 250/250 fibre line with Webafrica. Initially the price was R799 pm. They then sent me an email stating that the price would increase to R850 effective 1 October 2024. Today I received another email stating that the price would increase to R799 effective 1 January 2025. They have effectively increased the price by 12.5% over 4 months. Absolutely ridiculous!
