Reliance Digital — Apple Airpods

I had bought apple AirPods Pro online from reliance digital on 7th May’21 which were delivered to me on 9th May. When I opened the box, right AirPod did not have any sound. I registered complaint on phone with reliance customer care but they asked me to provide DOA from apple. Due to lockdown in Delhi, the stores were closed. When the lockdown was lifted, I got the AirPods checked and service report with faulty right AirPod was sent over email on 14th June. The team at reliance has not responded to my emails since and even customer cars on phone banking is not paying any heed now that I have the service receipt from apple store. I have been chasing reliance digital for return n refund of my amount but they are simply ignoring me and I have my hard earned money stuck with them. Request intervention.
My order id with reliance is RDF11336040
