Worst company to bring in your life

I am only selecting one star because it is not possible to not select anything. Worst network provider ever. I had a Data contract with them which they have been making it difficult for me to cancel. The contract finally came to an end in October 2021. Yesterday I was at a shop and was advised that I can’t apply for a contract because Vodacom Blacklisted me. I called Vodacom today and they have been cutting my calls since and when someone finally answered she said I owed them R10.00 I asked what is it for she doesn’t know. Okay how can I pay it 🤷🏽♂️She doesn’t know then she hangs up the phone. I am blacklisted for R10 which they didn’t even try to collect. Now my life is ruined for R10
