Consumer Redressal

I was given a quote of 16700 for moving my goods from Bangalore to Vadodara by "SouthNorth Packers and Movers". After the goods were packed from Bangalore home, Shifted to Bangalore Go-down, some guy from Bangalore called me asking for a bill of 30800 claiming the number of goods is more. I tried calling and talking to Mr. Sanjay Chauhan - person from south north packers and movers but he is not answering and asking me to talk to Bangalore person directly. Bangalore person is threatening me to pay the full amout (30800) or he will start charging rent of the luggage. Only after paying the amount, he will release the goods and transfer it to vadodara.
