Worst airline, terrible customer service!

Myself, my husband and our 2 small kids arrived at Cape Town international airport on Tuesday 27th of April departing to Durban. After checking in and taking our suitcases we were advised that we will not have a flight home on Sunday 2nd of May. I had checked on both my departing and return flights before leaving for the airport and everything was confirmed, no notification of cancellation. When I asked why I was not informed I was asked “don’t you watch the news?”. I was then sent to customer care and I was told there was nothing they could do to help me and that I have to book a flight home with another airline. The attitude of the staff member was disgusting and extremely unhelpful. I spent the entire day on Wednesday trying to get hold of somebody at Mango with no success, on Thursday I was told they don’t know anything and can’t confirm if they will be flying. I had no choice but to book with another airline and fork out R3800 which I had not budgeted for. Today I received an sms stating my flight time has changed so I called to advise I have already booked with another airline and cannot cancel. I was abruptly told that I would have to accept a voucher as Mango never confirmed my flight was cancelled despite what I was told by staff at both airports. You ruined a family holiday we had been looking forward to for months. You affected my job as I had to request another leave day. Your staff have no empathy and should not be working in customer services. What the hell am I supposed to do with a voucher? The least you people can do is extend the validity period. I have no intention of travelling again in the next 3 months. I could barely afford this trip with all the issues you caused. I will never ever book with your airline again! Please people, do not book flights with this airline. I will share this as far and wide as I can. I hope you get grounded permanently!
