Bad service by Vodacom on fibre and LTE contract(s) cancellation

I had a LTE contract with them which I renew and it ended on the 2nd of June 2024, yet there was an debit order of R247 which went off on a day they chose and it bounced and I was charged R100.88 for the bounced debit order. There was as a charge of R335.12 which no one can explain I have logged queries regarding this twice no feedback and it had not assigned to anyone and I notice it reflects that I owe them on my credit record but they are dragging their legs in sorting the invoice issue.

My advise if you want to join Vodacom just know when it comes to cancelling after the your contract ends just know you will make a lot of calls and it will be almost impossible to close any contract with vodacom
