Consumer Redressal

I contacted them to pick up my luggage from Bangalore and drop at Agra. They told me that charge is Rs. 45/ kg. They charged me for 50kg weight saying this is what your luggage weight is and then fixed charges over and above which they have not mentioned earlier. My luggage comes today and in receipt the weight is showing as 24 kg and i weighted it again , it is actually 24 kg only. They are now denying the fact and not refunding my extra money.
