DHL Express India — Laptop/ Huge amount billed as custom duty.

I have asked my friend to courier my used laptop from Netherlands to India because I couldn't travel back to Netherlands due to this crisis. While sending the package the entire documentation was done by the DHL representative and he declared the value of an used laptop as 600 euros.

My friend was not told about the huge sum which would be charged in the name of customs duty.
On Wednesday a clearance support agent contacted me and asked me to update the address even he didn't inform me about the customs duty.

On Friday night I received a mail stating that I had to pay 48000/- . First I contacted the customer care and they asked me to mail to customer care which was of no use. They keep asking me to pay 48000/- for an used laptop just because it was declared by the representative as 600 euros.

Being a student I can't afford the money right now and it was not completely my fault either. it's the duty of the representatives of DHL to provide all necessary information to their customers. I am even ready to prove that it's an used laptop but they are not ready to listen. I am aware about the customs charges but asking me to pay an insane amount is definitely disappointing.
