I would not call this customer care!!

On Sunday the 15.11.2015, I urgently bought a plane ticket to see my dying grandmother. She sadly passed away an hour later. I tried to call Mango, but there is no voicemail. I sent through an email requesting assistance&refund - to which I have not receive a response. I called the next morning to let Mango know asap. I was then told they will give me a voucher and the difference in cash as they do not do a full refund - ridiculous. I had the decency to call way before my flight, so that they could still let someone else book my ticket. I was then told to send a copy of my grandmother's death certificate - which I did. I was then told - \I will send your voucher tomorrow". Which did not happen. I had to practically beg for my voucher. Once I got my voucher"
