Cluessless about their own Processes - Waste of time and money

Horrible service from Vodacom continues for months. I requested a recording of my cancellation call and after many calls (at my own expense I might add) I was eventually told it's attached to my profile and I should go to a Vodacom store to listen to it. This is the same recording with proof that I was told I would have no further debit orders after paying early cancellation fee. Drove to a Vodacom shop in Somerset Mall to be told Vodacom consultants need to email the recording to the store because the store does not have the same access. Petrol wasted, airtime wasted. I'm so defeated. I don't know what to say to Vodacom anymore!
