Mango does not respond to their online inquiry submissions

<p>I bought a ticket for a friend and before the day she had to travel on Mango on a pre-booked flight, she fell ill and had to prospone the flight, but could not set a date nor a time and with Mango's limited optioins I submitted a requist to put the ticket on hold for the mean time untill further notice. It is now two weeks since I submitted a requist on their website submission form to their Headoffice and still no responce from their side? What is going on there at Mango and I am flying frequitly on their flights between cities, but if this is the service they give, I would rather go to another airline that take care of their clients.</p>
