Disgusting Service

I was late for my flight yesterday due to an accident that held up the traffic yesterday late afternoon. I went to the check in desk and advised that the gates was closed. they referred me the the query desk. The lady that assisted me was so rude and unhelpful. I than asked to speak to a Manager and was advised that the Manager has left for home and they do not give out contact details. How is it that there is no one to assist when you need assistance. I absolutely think that Mango's customer service stinks and will never use them again. i will also ensure to spread the word of their bad Service. I can not see how my ticket can not be refunded or they could of put me on stand by to assist. after all the reason for me being late was out of my control. I did not ask for an accident. Surely there should be some sense from Mango to assist people in cases like this. I phoned Mango's refund department this morning for assistance and was told to pay for a full ticket. Attitudes are absolutely discussing. No one is willing to listen and assist.
