I know this will not happen. But if in case I do not find any representative at airport to meet me as promised?

We recognise that this is the most stressful time in your journey. You are tired, you have just negotiated the various bureaucracies of India and there is a huge crowd of locals waiting to welcome their relatives. It is pretty forbidding, but we will be there with a placard. If we do not find you, then stand there looking lost and we will come up and check. Sweet coconut and we are on our way!
