KFC - they don't take accountability for customer experience

I lodged a complaint about the poor service I received at Rustenburg KFC two months ago, but I have not received any follow-up. I was charged twice for one meal, and despite raising the issue, nothing appears to have been done.

I am very disappointed by the lack of response and accountability. As a customer, I expected better service and at the very least an update on how this matter would be resolved. This experience has left me disappointed in KFC as a brand.
