Panasonic — Complaint for purchase of Panasonic Split AC 1.5 ton (HU18ZKFF5)

I have purchased Panasonic Split AC 1.5 ton (HU18ZKFF5) on 22 june 2023 Invoice No - 729 from Unique Enterprises Malviya Nagar New Delhi -10017.
After the installation I have been facing the issue of Noises from the AC and have made many complaints regarding this issue to your service centre . After multiple visits from your service centre there has been no action taken till date. On the last visit I was told that the outer cover and two swing/ fan motors had to be replaced to sort this issue out.
Please note that this is a highest model of 2023 and i purchased it keeping the brand value in mind but my experience with panasonic has been pathetic and unsatisfactory and your service levels and quality of service engineers are of low calibre and since starting i have been complaining on this issue to Mr.ganpati aircon/Raghu service head vasant kunj phone no. ([protected]).From past 3.5 months he has been assuring that he will get this inner unit replaced as this issue has arised since starting after the purchase of this product.
Every time I have given a false assurance of getting the issue resolved but no action is taken by him till date. From past 1.5 months he has stopped responding to my calls
sir, please tell me after spending so much money i have been sold with a faulty unit and this should be replaced on an urgent basis and this issue has already been highlighted to unique enterprises earlier.
I request you to please get this issue resolved asap with a replacement of the product or the inner unit.
waiting to hear from you on a positive note.
