No go orders

I ordered some snacks from a convenience shop and there was a item short from the checklist. I took the issue up with Uber eats afterwards, but to no avail. They refused to refund me, even after providing proof of the shortage claim. Spoke to the courier as well, and he claims that the shop didn't receive the correct quantities for said order. Contacted the shop, with no reply from their side. Inconveniencing me and dragging me from pilar to post. Be very careful when ordering from these people. They aren't very helpful in resolving issues, and keep on giving automated responses, no matter what you say. Seems they like to ***** from people. Not the first time I'm having issues with them.
