Good Location but very very poor staff

We booked for 4 nights in a Luxury sea view room and paid extra thinking the word “Luxury" meant the room would be an upgrade from the normal room. The room was exactly the same as a normal room but facing the sea view, mind you all other rooms have the same view, just rotate your neck 30 degrees and you see the same view as from the "Luxury" room, total marketing rip off, please don’t fall for it!! The rooms were very disappointing. The plumbing work in the toilets is a mess, clogged sinks, shower drains overflowing into rooms. We complained and were promised a visit by the maintenance team. No one turned up for 2 days. After getting fed-up with the service we decided to upgrade to a 1 bedroom villa with a private pool.. and paid extra because we did not want to ruin our trip due to bad room and bad service experience. Due to late flights we organized late checkouts, again of course we paid extra for it.. At exactly 6pm the hotel front desk sent the bell boy to collect our luggage. As we had children with us, we were running bit late. This caused a major issue with the front desk. We had 4 people standing outside our door to throw us out. All this was due to us being half hour late. The front desk staff whatever his name was being rude to the point that i almost beat him up. We spent a lot of money in this hotel with the upgrades, late check outs and the ridiculous amounts we spent on food and drinks at the pool bar and room service. This kind of staff behavior in the service industry is totally unacceptable. I left the hotel totally shocked with the staff's attitude. Having traveled extensively throughout the world.. i have never experienced this kind of behavior from any hotel staff anywhere!! So, if you are looking to get humiliated by the hotel staff, please plan your next stay in Kho Sumui at KC beach Hotel, you will not be disappointed.. bad service is guaranteed.
