It’s overheating without licking somewhere

The AC of my car doesn't work and the fan keeps running loudly. I gave it for service at the authorized service station and the mechanic said that the AC heater core is damaged. The thin aluminum box is broken and the coolant is dripping inside the car hence the fan is running continuously to cool down the engine. The cost for replacement is estimated to be INR 9000. Is there a way we can get it at cheaper price?
