OnePlus India — One plus bullets wireless Z bass edition

I am having a worst experience while claiming warranty of my device(REF ID: WEOSDTBX5XKU). It was picked up on 13 oct 2021 for repair, after pursuing for about a month i have still not recieved it. Even customer care people have no information. They just keep on asking for more time from me. Their application shows that device is under repair, but how come it is taking a month to get repaired. I had to buy new handsfree because of this. I do not know whether i will get my device back ot not.i felt cheated.
