Ok it easy . I booked back koh Kong to PP . On 08 January 2018 2 pm by VIP.
Very unpleasant experience. Paid for an express van, got a bus instead. Information on e-ticket was completely wrong, both departure point and arrival point. Uncaring staff. Arrived hours late and angry.
The adress of the location of departure in Phnom Penh on the ticket was incorrect. It was the adress from where Virak Buntam minibuses leave, but not the big bus we booked. We needed to take another tuktuk to get us to the right departure place.
