Very poor service

I have lodged a query on vodacom on the 19/07/2021 Query number *** - The query was that vodacom has upgraded me to a package without my approval and billed me for that contract I have tried on numerous times to correct this without any luck. I was given a date by which it would be resolved that date has passed and I phoned in to hear if any progress was made The agent/agents working on my query was Phalatli and Sue Ncube Nothing has been done on my request

What do I need to do to get this solved as I had enough of your incompetence .

If this is not resolved by close of business 27/07/2021 I will unfortunately log a complaint at the ombudsman for wrongfully debiting my account
