UNACCEPTABLE SERVICE DELIVERY

In the early hours of the 30th Of August 2015 my grandmother passed away, I then tried to book a flight with Mango as they had the soonest available flight. I received a technical error message TWICE and as this was an emergency I booked a flight with another airline as no confirmation from Mango was received. I then received a notification that Mango had debited my account TWICE for the same flight. In the midst of their being a death in my family I had to call Mango every day to ask what the hold up was with the investigation, explaining over and over via phone and e-mail that I never took a flight with them. I have now reached my limit as I have been told that my refund will only be received on the 26th of August. I don't need to explain that flights are not cheap and I am now bearing the brunt of THEIR technical difficulty for almost a month! I will never ever fly with Mango. Ever!
