The OP is in Borneo. I am not familiar with the common instructional practices there.
When I was still a fairly new diver, I did a series of dives with a shop in Fiji. One day a young man from the Netherlands dived with us. He was obviously very new, his skills were very week, and I was surprised the DM did not pay more attention to him. On each of the dives that day, he went through his air very quickly, and the DM sent him to the surface alone. I was surprised by that--pretty trusting for a clearly unskilled diver, I thought. On the second day, he was no better on the first dive of the day. We had hot dogs cooked on an island during the surface interval, and he overindulged. He did not do the second dive because of his bellyache.
When we got back to the dive shop, he as greeted on the shore by someone I had never seen before. While I was still rinsing gear, he came out of the shop with all of his paperwork for his brand new OW certification. The man who had greeted him on shore was his OW instructor. The two days of 2-tank diving he had done with us, including the dive he skipped with the bellyache, were his 4 OW checkout dives. No skills performed. No instructor in the water with him. No instructor even on the boat.
I switched to a different operator for the rest of my trip. I reported this to PADI, and they did act upon it.
