Terrible service, think twice

Be very careful if you want to make changes to your booking, because they have a way to rip you off. I booked a return flight Cape Town to Durban, due to change in circumstances, I wanted to change the on going flight time, I started changing the time online via manage travel, the system asked me to top up the flight by R832 since there was a price difference of the new flight and a service fee, as I was busy with the SID payment I realized I didn't have enough money. I called to cancel the change to the original time, they said they can't do that, I have to pay the outstanding amount. I started searching for alternative flights, luckily I got a cheaper flight, that I booked for my trip to Durban. Now the chaos came in when I had to return, I proceeded confidently to the Mango check-in desk knowing that I had a return flight booked and waiting for me. I was told that I need to pay the R 832 in order to board the flight, I told them I never made changes to the return flight, I never changed the times to that flight. I was told that I made one booking, there is only one reference number, even though the change was for the on going flight, now the return flight is affected. I got the shock of myself. I paid for a service, I never changed the time for my return flight but somehow now it is affected. I can not wait for a day when we have proper regulations to stop airlines like Mango to treat customers so unfairly. Thank God we have another affordable airline on the market, Flysafair, now Flysafair has become flight of choice. I don't see myself flying with Mango again, due to the terrible experience I got when I was trying to resolve this matter with their staff. I never got a refund for my return flight, I was not allowed to board a flight I paid for. If you want to test a business that cares about its customers, try and evaluate how they deal with customer's challenges. Think twice before you fly with Mango, because cheap can come at a price too.
