Xpressbees Logistics — Fraud done by courier boy

Hi Team,
We have used xpressbees for a shipment delivery with AWB No- [protected] which was delivered to us on 6th JAN.2021. Now what we shipped earlier was 2 wrist watches which is mentioned in the images shared below. Now the order was RTO return where customer had refused to accept the order and thus it was returned to us. Now when we open the product we had found that both the wrist watches was missing and a empty parcel was returned to us. Also we found the return packet has tape wrapped around which was not done by us and clearly proves the product was returned to us tampered. I am sharing the opening vedio of the product and images and want your team to raise this as my complaint and investigate and tell me what can be done in this case as the products which were stolen was expensive and created a huge loss for us.
