Panasonic — My AC air blower sounds a lot from day 1

Hello Team,
I purchased two Panasonic ACs on 28th April 2021 from R. S. Distributor Mathura in which one was making too much noise, For the same I raised a complaint with complaint number R[protected] and for that one Service engineer came and told that it's fan should get replaced and he told I'll get it replaced and never came back.
Now again when we raised a complaint and service, The same service engineer came and he told the same thing that the fan should get replaced and he talked to service centre and service centre guys are refusing to change the fan in warranty. Also not a single service has been done even after raising the request
This kind of disappointment was never expected from Panasonic, I expect my issue will get resolved here

Thanks
