No communication from Mango Airlines despite several reminders

No response from Mango. Despite sending three emails. Unable to get through to customer service on line as obviously so many people need to speak to them. Issue with changing bookings on line - on phone or on internet - so resorted to having to buying brand new ticket at a great cost.

The ticket that I had wanted to change was then forfeited as I was unable to change.

Went to desk at Cape Town airport and then wrote a list of all the issues but still no telephone call and still no email!

I am extremely disappointed with the lack of service and would ask that they should not accept any more bookings until they have storted out their issues! I wish to be refunded for my ticket and at least receive a phone call and email.
