Poor customer service @ Hotel Sky

I always only have good things to say about Sky hotel from previous experiences, however my views has since changed. I just got off a call with reservation around my booking preferences and the way Melanie spoke to me was like I'm a small child who do not understand the difference between a major and a minor. Rudely spoke over me as though i didn't understand plain English. Its either you can accommodate my preference or you cant. What is worse she suggested that I select a room to separate my family, we are a family of 4, this is not optional and is unconventional. Please provide training on customer service, this is definitely needed.
