Beyond shocking

I downloaded a free app on apple. After the 3 days the free subscription stops and the app wont work. Vodacom has however sent me immediate notification that highest bill subscription will be billed and should i not wish to be billed to call the number indicated. After doing so the voice message i indicated that i called after hours but i was 9:30 in the morning. Needless to say that was a waste in time. I then got another message that i am now going to be charged for the free Vodacom app. What js going on Vodacom. I tried to call the help line just to stumble through 100 voice prompts to eventually be told that a bot will assist me via WhatsApp . Well i am still waiting . What is going on.
