Knowing there might be a wait at immigration, I chose to set my own pickup time when booking. I scheduled the pickup for about an hour after my flight's arrival, and with the driver's 60-minute waiting period, I figured I'd have plenty of time to clear customs without rushing. However, I booked just 5 minutes before takeoff, and after landing, I realized the pickup time had defaulted to my flight's arrival time. I'm certain I selected a specific time, but after doing so, I'm not sure why I still had to fill in the flight arrival information (which I did). I suspect there might be a system issue. After entering the Philippines, I checked my pickup details and found that the system had determined my chosen time was based on the flight's arrival at the destination. Immigration took a long time; my flight arrived at 11:05 AM, but I didn't clear customs until 12:10 PM, which was a bit over the scheduled time. The long wait made me very anxious! I was worried about extra charges for overtime or the driver leaving, and I couldn't reach the driver, which added to my stress! I'm very dissatisfied with the Klook booking system and hope this issue can be addressed and improved! Aside from that, there were a few things I found excellent. First, I immediately contacted online customer service. I didn't have to wait long before a representative was available to chat, but before the issue could be resolved, it was my turn at immigration. The customs officer told me not to use my phone, and thankfully, I wasn't given any trouble entering the country. After rushing through customs, I was relieved to see a Klook representative holding a sign, waiting for me. She led me to where the driver would soon arrive. Although I was late, I wasn't asked to pay any extra fees. I asked the driver if he could take me to a currency exchange, and he kindly agreed and patiently waited for me to exchange money, so I tipped him in return! The driver was truly wonderful, and I'm very grateful to him. The Klook representative who met me was also very kind, friendly, and proactive in her service. Many thanks to both of them! ❤️
