DHL Express India — [protected] awb

I have been asking for my MWAB copy and they never replied to that email and then charged customs and duty of 49 k for products which I bought from India in India rupee where I have even submitted them the bills of the products for proof of purchase from India. These items were my personal belongings for more than 2 years so it’s almost very much used products for that they blindly charging on my custom fee. I came from UK due to health conditions and it was an emergency so sent it through a courier parcel . And this where I ended up. Kindly help me on this to waive my duty and fees on the items which are my personal items using for years and brought from India.
