Too good to respond to any queries

<p>Mango Airlines have thought it good to change the date of a flight that I've booked for my daughter. The flight was booked so that she, as the eldest granddaughter, will be in time for her Grandma's 80th birthday. I wrote a very nice e-mail and had no response. Then went to Twitter - still NO response. At this current moment I have resent the email and reacted on Twitter. No one had the decency yet to contact me or respond to my e-mail, menaing that my daughter will miss a very special family occasion. Does Mango only care for money or does the customer count for anything???</p>
