Panasonic — New ac repair hardly used2 hours

I have bought split AC in the month of March 2022 . After AC instalation we have identified issue and registered complints. After so many visitings by panasonic service persons they said problem with indoor unit i.e, found leakege in indoor unit. hardly used 2 hours.Almost 50 days completed but still the issue is not resolved yet.
Now they are saying that we will repair the product, As a customer how should we agree with that.
panasonic technicians are not fully trained.
