Garudavega Courier Services — Disparity in courier charges

Address:

No.247 "PAVAMANA" 4 TH MAIN 2nd Cross, BEML 4th Stage Rajarajeshwari Nagar

I sent approximately a 12 kg food items to USA California on 14th February 2023.I am residing in RRnagar Bangaluru and called the local agent to pick the courier box.He came. Measured the box and told it will cost me ₹12450 for express delivery. And the money was sent through UPI to the number suggested by the agent. But till today he has not given the bill in spite of asking several time.But the rate mentioned in your web for 12kg courier charges to USA on express service was only ₹9517.
I would like to know the reason for not furnishing the and the changes ur agent collected from me.
There was a package of item which was not allowed to send(betel but powder).The agent told that it is allowed and in turn i expected him to return the package but still it is coming.
