I recently experienced significant inconvenience during my stay due to issues with your room service ordering system. I placed an order using the QR code provided in my room, only to discover that the staff member who responded was completely unfamiliar with the menu items I had selected. Subsequently, a different staff member called for confirmation but also failed to understand my room order. Ultimately, I had to resort to ordering from a different restaurant via the Grab app. This incident suggests a lack of proper training for your staff, leading to a disappointing and inefficient use of my time.
