Riverside Sun Bad Service / Attitude

I've booked accommodation at Riverside sun. On arrival at 1pm while waiting for other people to check in, they informed us that it will take about 45min. We said is fine, we will have a drink at the pool and asked if we can store our luggage with them in the meantime, which they accepted. We returned 1 hour later and asked if our room is ready, he phoned to check and did not get any response. He ask us to wait a minute while he checks. After 5 min her returned walked right past us, called us to the reception desk and informed us that the the room is not ready.We ask when the room will be ready and the response was that check in is only at 4pm as per booking confirmation (Still can't find any check in time on the booking confirmation, only dates). We asked to speak to the manager which they provide us an number to phone. No attempted to even call the manager from their end. After a while of arguing we manager to get a room that was ready that we could check into. We were moved from 6 floor to ground floor. That night we ordered room service only to receive cold food. Next morning after a 30min long breakfast que and still not serviced we checked out.
