Burger Mob Morningside, disgusting burgers

I ordered the Walter white buy 1 get 1 free special via uber eats.

The burger bun was stale. The advertised said it came with a creamy mushroom sauce, I got plain fried mushrooms.

I payed R95 for this special and it was utterly disgusting. One of the worst burgers I've eaten in my life.

I did complain through the uber eats app but nothing was done about it
