Trackon Couriers — broken products even with most expensive delivery

Address:

1971 Valencia, Mahagun Moderne, Sector 78, Gautam Buddh Nagar, Uttar Pradesh, 201304

I sent 3 boxes with an approximate value of products of 12000 rupees. But due to Trackon's mismanagement, all the products got broken. It was sent with one of the most expensive delivery just to ensure safety. Also, products were covered with bubble wraps and double cardboards.
It is clearly visible that the boxes were mishandled by the delivery partners. They are highly unqualified and unprofessional personnel. Even on the boxes, it was clearly mentioned that the product is delicate and needs proper handling.

I need my refund back for the products broken. It cost around 10000 as a whole.
