JBL — JBL bar 1000mk2 - Faulty Product Delivered, Subwoofer Producing Wind Noise Instead of Bass, and Poor After-Sales Service

Exiting complaint ID for which there is no proper response: KA-C[protected]

I received a faulty JBL soundbar, and the subwoofer produces a wind-blowing noise instead of the expected bass. Despite raising a complaint, JBL has failed to arrange a proper service engineer visit to diagnose and resolve the issue. The scheduled appointment was missed, and there has been no proper response or communication from the service team.
I purchased this premium product for over ₹75, 000, and it is extremely disappointing to experience such issues within less than 20 days of purchase. I even took leave from work to accommodate the scheduled service appointment, only to be left waiting without any resolution.
The product is faulty, and the after-sales service has been equally disappointing. This is unacceptable for a premium brand like JBL.
I expect JBL to take immediate responsibility, arrange a proper technical inspection, and resolve the issue without further delays. If the product cannot be repaired, I expect an appropriate replacement or refund.
I request immediate attention to my complaint and a concrete resolution instead of further delays and empty assurances.
