Symphony Limited — Water coming out of air vents.

When the water pump is on, water droplets are coming out of the air vent. I had complained about this issue about few days back and a customer support executive also visited and repaired the cooler. Again the problem started and I have to switch off the water pump and only hot air coming out it is very difficult to bear the heat of these months. My warranty period also coming to an end and since 1 year after purchase of this cooler I have to call for warranty 3 times.
I don't understand that a company like Symphony which is number one company in this air cooler market is manufacturing such type of defective products.
Please help me as soon as possible.
