paying liberty rent and no aircon

We have been a tentant at eastgate office towers for more than 5 years and have been paying our rent every month. We now for the last 6 months not had a aircon working more than a day. We have contacted them more than I care to mention and still we have no working aircon. This is clearly bridge of contract and we now are wondering why I should pay full rent if we dont receive the full services. On top of it all the building has been without water for 2 days as well. Is this how liberty treat their tentants. Get your act together and resolve this. <br>
