Pathetic service and borderline theft

On 19 December I ordered food via Mr D at Fireplace roadhouse. My order received on 3 waffles were incorrect to the value of R63. Ordered bar one waffles and received plain waffles

I immediately logged a dispute vis Mr D help function and also send fireplace roadhouse a message. The roadhouse manager called me a while later apologising as they checked their cameras and verified they sent the order out wrong. But due to ordering through Mr D the refund had to be done by them.

A couple of days later still had not heard anything back from Mr D. And I logged another dispute

It is now 12 January. It is nearly a month later and still no contact from them and no refund.

So basically Mr D stole the R63. As now it seems I just have to make peace with not receiving the refund?!
