VRL Logistics / VRL Group — Non delivery of 4 wheeler

I have shifted my house holds along with 2 bikes and 1 car through VRL PACKERS AND MOVERS on 5th october via a quotation of Ts 35000/-
The goods were loaded after packing along with 2 bikes and car was sent in car carriers from Bangalore.
I have received my house hold goods on 6th october .Then without delivering my car one person named Rahul gave a bill of Rs 70000/- against the quotation of 36000/-.
They are now charging double the amount and not delivering my 4 wheeler.
They are telling to clear the bill for car delivery.
This company is a fraud company and not returning my car.
Kindly help
