I had a very unpleasant stay at "Best Western Premier Dua Sentral", in Malaysia, Kuala Lumpur.
When i complained four times over a period of a day and they still did not even try to solve my issue i wrote down the story as a review on some hotel-review sites. Now it seems like Best Western are paying sites lite tripadvisor for removing unwanted reviews. That is not very nice behavior from a hotel chain who claims to care about the customer.
