Customer Service - Should be NO Customer Service

I reserved flights for a business trip to WTM Cape Town for 2 persons on 11 March 2020. Unfortunately due to the Corona Virus the event was canceled and we have all been advised to cancel non-essential travel. I sent an e-mail to customer support and received no reply. I called the Customer Service today and after holding on for 35 minutes someone answered and simply put the phone on their desk. They continued chatting and laughing in the background and after another 10 minutes they simply hung-up! This is the first (and last time) I have used Mango. Absolutely not acceptable service. And I bet they do not respond on this Forum either.
