They installed an air conditioning unit a couple of months ago and it has never work for long so they keep sending repair guys out but they never fix it and instead just seem to get it working for another couple of weeks and then it stops and we start all over again.
Also very difficult to get the repairs guys to turn up on time and instead you just end up standing around waiting for them to show. They wont call to inform you of delays or cancellations.
Would not recommend!
