OnePlus India — Damaged Headphones not getting repaired or replaced

Hi,

One plus Bluetooth headphones are not clear during phone calls and during media it is being taking a pause for few seconds. I have already sent to service centre twice but the same headphones is again and again sent back to me without repairing. I would need this rectified or replaced or refund immediately as it's being 2 months I am trying to solve this issue but headphones are returning back to me without repairing. I would need to close this ASAP or else I will take next step which you guys will have to face the consequences.
