DSTV lack of primised refund

On 23 August 2023, I wrote a DSTV billing review on how it had taken more than a week to get DSTV streaming going. Eventually Danaphile managed to resolve the issues and promised me a refund for the amount incorrectly billed to me by DSTV. It is now 22 November, 3 months later, and there has been no refund yet. Why is this the case and why does DSTV promise things they don’t deliver. Please DSTV, sort your issues out - billing is a common complaint on this platform.
