Telkom double charging and not holding employees accountable

@ Telkom I did an upgrade in March and as usual capped my billing but they sent me an invoice double my contract. When I contacted them, they said it wasn’t capped. This was like after spending 20min with the lady on the phone she told me their systems are acting up she can’t even see who did my upgrade, it’s just some funny numbers. This was the response I got when I said you hold that individual responsible and as you would say our calls are recorded, listen to those cz I sure as hell ain’t paying double what I was sold and agreed to.
