Months later, and still no refund!

Tudortech Cape Town has owed me a refund since the end of January 2025 for charging a service fee on a Dyson vacuum cleaner that was still under warranty. I have been following up via email and phone call for over two months now, and keep getting told that they will follow up with their accounts department and get back to me - which they never do. This is not only poor service, but verges on the u n e t h i c a l. Having exhausted all other options, I will now be lodging a case with the National Consumer Commission.
