GoAir — grievance faced with luggage

My wife along with 2 year old daughter was travelling from mumbai to cochin on sunday 22 jul 18 from go air airline g8-336 with two bags in luggage. She checked in at 1455h, 2hr prior scheduled departure at 1720. On reaching cochin, she received only one bag. On enquiry with go air staff at cochin, we were informed that the bag has been held up at mumbai airport as it contains a power bank. We clarified that we do not own a power bank. On further enquiry with go air staff at mumbai, they informed that the bag contains a bullet and hence has been held up, for which the passenger has to come to mumbai to claim the bag. We brought out that why this information was not brought to our notice when we were waiting at mumbai airport for 2 hrs. They kept on giving us vague answers and excuses for their mistake. They threatened us saying that if we don not come to mumbai for claiming the luggage, it will be handed over to civil police. They forced us to travel back to mumbai, and spend rs 22000. On reaching mumbai airport on 24 jul 18, they handed over the bag to us and on enquiry regarding bearing of our travelling cost of rs 22000 from cochin to mumbai while on duty, no body was able to answer us properly and again kept on giving excuses. Go air staff also made us to write a mail giving authority to their staff for opening the bag, however, they dint do it and forced us to travel to mumbai. If they would have informed us on same day, issues would have been sorted out then and their itself and we would have faced the financial loss. We have written mails to go air grievance team, however, no response received from them. This incident caused us lot of mental stress as also financial loss. Our urge to consumer affair team to look into the matter and request them to compensate our travelling cost.
