Hi,
I Think there are No solutions at all.
In Feb 2017 , Bluedart charged Rs.3050 for my 80 gms heatsink compound that cost Rs. 485 !!!!!
I sent several mails to ebay. No reply.
The best way is to quit powership.!!!!
recently I started verifying powership charges in my report.
I found many wrong weight cases - charged excessively.
