Maruti Suzuki Nexa — AC not working (Air not blowing through one Port)

Address:	Hoshiarpur
Website:	www.nexaexperience.com/contact-complaint

I have purchased new XL6 Zeta MT model in the month of May2022 with registration number PB07BE4444, and within one year AC working issues started as out of 04 ports given on dashboard one is completely not working (no air through this port), I went to raise a customer complaint but failed as Nexa website has not entitled Punjab as state and Hoshiarpur as city in their drop down list for dealer information, then i called customer care of Nexa and after a long conversation they also denied to file the complaint.

So i want complete analysis of failure of product function as it is most critical category defect of product with the solution / rectification.
