NO REPLIES ON EMAILS!

I flew with Qatar to Lisbon. My suitcase handle broke on the way in the luggage transit to Lisbon. I have travel insurance. I cannot log a claim without a reference from Qatar Airways. Since October I HAVE HAD NO REPLY. You can email every single day, it just gets IGNORED!!! Pathetic. Answer your emails. You cannot just accept money for flights, customer service and the rest comes with running an AIRWAY!!! What the hell!
