Vodacom fibre / zoom fibre discontinued

So today most vodacom customers got a whatsapp stating our current lines have been discontinued and as of the 1st of May 2025 we will be migrated to the next available package. Now I signed up in February for a 24 month contract which stated I will be billed R299 for the first 6 months then from month 7 R369 for 20mbps which I agreed to and can afford. Today the 25th of April 2025 I learned vodacom is moving me to 50mbps which costs R689 and as of next month being May I am supposed to pay this amount for the next 22 months until the end of my contract. Vodacom is so wrong for unfair business practices and ****ming us by doing this. I will lodge complaints with every avenue I can find because I have a contract in black and white and it's not my fault as the consumer that zoom is discontinuing the 20mbps line and we being forced to higher speeds which I didn't even ask for plus the price is ridiculous I can't afford another extra R400 because of vodacom. We should all boycot this service provider for false advertising and breaching contracts with customers. Sis Vodacom shame on you.
