Worse bad service in the world.

After being a loyal customer for more than 20 years with Vodacom,i recently received a worst bad service.On the 12/02/2024 I phoned Vodacom to get help because i was overcharged.I sat on the phone from 10.00am until 18H00t. Eight hours. I spoke to almost all the departments and all the call centre agents.I didn't get help. It was like I was speaking Greek.I received different explanations. Finally my call was picked up by a call centre agent called ZINTLE JONI.She picked up the error and sorted it within minutes.She is patient. Professional and respectful. I was receiving 1000 minutes per month.I want to downgrade to 500 minutes per month.I get different explanations as to why it can not be done.
