Hundai Santro XL
AC condendor damage

I purchased new Hundai Santro XL in Aug. Recently after paid servicing I noticed my car AC is not cooling, then I sent my car for repeat complaint to nearest Hundai aauthorized service center, that

Concept Hundai, S.G.Road, Ahmedabad. After inspecting the car they told me that my car's AC condensor has minor crck due to any stone hitting accidently. I have to replace it with new one costing 7000/- apprx. But i am not convinced that within that short duration how any new car's AC can be damaged. If that thing is so sensitive to be damaged then all cars would have been faced same problem, but there is very rare cases are there. Kindly send my complait to Hundai company, and let them sort it out properly.
