Vodacom increases their contract fee every month!

Hi guys. Please take a minute and go through your Vodacom statements. I just found that Vodacom has been increasing my amount on a data plan little by little. When I took out the data contract in March 2024 the amount was R249 and they have increased it little by little and now the amount is up to R300. This is what you call *****ing! Of course, you email them, and they don't get back to you and phone them and have to hold on for 15min and your call gets cut!!!
