Found this company in the Tourism Authority of Thailand website (for a reliable operator) under a different name. And indeed it did fulfil its obligation to provide the tour on the same day. My morning tour van was filled by a group of 10 pax, and by a-day-prior email notification I was reassigned to the afternoon tour to join another tourist arriving in Phuket in the early afternoon. There were only 2 of us in the afternoon tour meant for 10 pax and they still proceed to fulfil their orders.
The tour guide Micky and driver even put in the effort to pickup the lost tourist who's airport taxi had dumped him in Patong after failing to locate his unknown B&B accommodation whose name has changed and address cannot be found on Google Map. And after the tour sent him to this B&B house.
Of course these cause me delays. But they still complete the tour itinerary.
Complementary fruit juice, 2 bottles of water, coffee, biscuits and a banana were provided in the tour with adequate toilet breaks.
Tour guide Micky speaks very good English, is a local, takes very good photos and has a good understanding being a frequent tourist himself.
