We were travelling on indigo flight no 6e 89 today from dubai 0910am to calicut 10.00am and at the belt no 2 we found missing one luggage with tag no [protected] out of three luggages carried by us. We repoted to the luggage desk with a form filled up and got the signature of a customs officer. We were told to contact [protected] and [protected] and i found no response so far from these nos.
There was a leftout luggage with tel no[protected] on it and when i contacted he says he only helped one ayesha and kasim. To book this ticket to calicut.
