Consumer Redressal

I shifted from Pune to patna . I am being mentally harassed by the packers movers, I chose . I used Gati packer and Movers with Ramesh as contact point(9284546941) and paid the amount of 55K. I sent my luggage on 30th August, but I am yet to receive it and it is 11th September today. In addition to it, both Ramesh and the luggage handler , Ratan (7503977775) is not picking up my call from 4-5 days. Ramesh never picks up the call , he would only recieve when he wants some payment but now ramesh is also not picking up the phone. They have not shared any information of the driver or contact person at Patna. I am totally clueless for the next step with 44K payment already done. few days back when I asked ratan to let me know the status, he told that his higher authority are asking me to do full payment , otherwise nothing will be delivered. Where as , it was explicitly specified that 20% of total amount will be paid after the delivery. In fact the main guy ramesh agreed himself that rest amount will be paid after the delivery. Please help, we are in the new city and very frustrated and disheartened.
