Extremely bad service midst a problem

I was highly aggrieved and upset at the service rendered during my flight yesterday on Air Mauritius departing for Johannesburg.<br> It is expected that delays will happen from time to time and also extended delays as we experience yesterday with an almost 7 hour delay on our flight. <br> What is not expected is the no-chelate attitude of the crew and no visible management presence or communication. <br> More shocking was to hear that the problem with the plane was known to the airline the day before and although attempts to repair the plane were done it still resulted in a 7 hour delay after an eventual plane change. (Could this not have been managed better ?)<br> Passenger (all who got up at between 3/4 am that morning to make the flight) was stranded at the airport including several families with small infants. The only convert presented from the airline was that of small snack and coffee (communicated as breakfast). <br> On the flight attendant barely wanted to make eye contact sensing the atmosphere with the passenger at this point highly irate.<br> All previous good experience with the airline was shattered by this poor handling of a very common and understandable problem
