I'm deleting Talabat

I ordered stuffed donuts for school and specifically ordered non-nut options as we cannot bring nuts in; this cost 60 AED. They ended up having half the order as nut options, which I'm not allowed to take. They offered me a partial refund of 15 AED, though they should be giving 30 since half the order was messed up. I tried reopening the case but they kept closing it again saying the refund was given and it's resolved. Absolute BS; what if I had a nut allergy??? Half the donuts are worthless.
