Truecomretail — Refund request rejected without informing me

I bought a Galaxy A71 from flipkart, but it has a faulty display. I requested for a return flipkart said that the a technician from the seller side will contact me to verify the issue and he asked me to check the issue. Then the technician contacted me and asked me what was the issue and I explained and send him a photo as he requested, then asked me to check the android version which is the lates version android 10. But he tried to convince me that the version that comes with this device is 11. Something, I confirmed with the samsung service desk that there is no mobile comes with the version 11, it is not even released yet. I'm not satisfied with a approach from the technician. Then he asked me to perform a reset after resetting the phone I tried to contacted him back he never picked up the phone and after some time I received a message states that they tried to contact me but I did not respond and they will close it within 48 hours, actually I did not receive any call after resetting the phone but the technician was picking up the phone when I called him back. I called to the number which they provided in that message and they said they will come and check the issue by 1st September 2020 but when I checked the flipkart on that that it showed as the return request has been rejected and they did not contacted me since they told me that they will visit me by 1st September but they rejected the request without informing me. Now I again requested flipkart to rssolve this issue and they said they will resolve this by 4th of September. But I Don't believe that the seller technicians are doing the job ethically. Kindly advice them to approach customer properly without misleading.

I'm looking forward for a solution.
