NO CUSTOMER SERVICE

I had an account for more then 6 years now where Vodacom has not billed me a single thing from 2023 till Aug 2025 where I was then billed all of a sudden with a higher amount then what i signed for . I have phoned, emailed and even went into two separate shops to get a explanation for what happened, how this happened and why so that i can have my account sorted and closed with each person having a different story. Now with 5 queries opened already they decided to hand me over and take legal action. I have not received any feedback or any communication from anyone at Vodacom not now and also not before I had this issue. I was never informed that something was wrong in the past or why I was not billed and every phone call ends with a agent will look into this and get back. This is not at all acceptable
