Lies and more lies from Vodacom

This is my third complaint regarding the same issue. Vodacom agents don't keep their promises...

The agent gave incorrect information. They listen to the calls and confirmed as much. They try to push it under the table.

The manager calls me and promises this is resolved. Will reflect in 7 to 10 days...

I get billed again for the incorrect amount. This is the last straw. Im tired of empty promises.

I want my money back Vodacom. If not please provide me with the ombudsmen and all my calls.
