Upon departure from Delhi, my wife discovered her in flight entertainment did not work, we upgraded to premium economy for a better experience, but it was not to be, such a long flight with no entertainment was very boring, especially as you can see everybody else around you enjoying films and entertainment. The cabin supervisor said he would put a report in and we would be contacted and compensated in some way, and he further advised us to complain, which we did. I made that complaint on 26th March. We have heard nothing from either source, so last week I went on live chat to ask for an update. The person I chatted with asked me for my reference number, I told him I had not received any form of acknowledgement from my online complaint, and he said when I filled in the form it would have generated a reference number, which I should have noted and saved. I'm afraid I did not realise I had to do that, so I did not have a reference number, so I asked him to look up my complaint from my personal details. Unbelievably that cannot be done, unless you have the reference number, your complaint cannot be traced, you cannot even find out if they actually received it. What sort of company has systems that do not populate the complainants details for reference, I know of no other company that can only access a customers file/records from a sole reference number. The online chat ended with the agent inviting me to go back online and make the complaint again, and that I should be careful to note the reference number this time. Absolutely Hopeless.
