Very disappointed hungry customer.
I am highly disappointed by a major glitch in your system today (9 Oct). I ordered GrabFood for self-collection at 6:11 PM. When I went to collect it at 6:30 PM, the staff told me my order didn't exist in their terminal—yet my app clearly stated it was ready for collection. Leaving a hungry customer stranded without any solution due to your system failure is ridiculous. Please look into this technical error.
