Very bad service-Dissatisfied customer

I had an air conditioning unit installed in my home by KC Aircons(whom I believe is one of your buyers), on the 16th of December.<br> I then left on holiday on the 18th of December, and when I returned home found the unit not blowing any cold air. I then reported this to KC aircons on the 4th of Jan , to be told that a supplier technician will come out to me last week Thursday, however to no avail.<br> I then contacted you guys(capital air) on Friday the 8th Jan and spoke to a lady by the name of Azema, who assured me she will try to get someone to me on Saturday , no -one pitched. I called back yesterday , to be told that someone is definitely coming to me and yet again no one pitched , neither did I get any phone call.<br> I was then told another supplier will definitely come out to me on Tuesday , then Wednesday , then definitely Thursday , and still nothing I basically paid for a brand new aircon that does not work ,I was also promised cabling that was never done.Is this the after service you offer your clients?<br> I installed an aircon for a specific purpose which it isn't doing right now , I am very dissatisfied with the service I am receiving and if this isn't sorted , I want a REFUND
