Karnataka One / Bangaloreone — Demanding high charge for the service

Address:

"Bangalore one" gottigere branch, near bannerughatta main road

"Bangalore one" gottigere branch, near bannerughatta main road, person is charging high for the service, recently i approached this branch for aadhar address update of my wife through head of the family(we only husband and wife) with all necessary document, he checked document (marriage certificate and aadhar) he is said ok to change address to husbands aadhar address.
I asked the fee for update, he said 600rs, i asked him online it is showing 50rs why you charge that much, he asked how much will you pay, i said 50rs + 150 for applying, he said no.
So the service is not done.
This is what happened, kindly take necessary action on this, how will poor people afford this fee.
I also take this matter through mail to concerned head of the department.
Thank you..
