Absolutely disgracefulness and ***** business from Mango.

First I made a booking with mango airlines which ended up to be the amount of R6176.00 then the lock down came and I requested a voucher for the amount of the R6176.00 which they gave me and all was happy. After the lock down was change to level 3 I needed to fly to JHB from CPT again for work. so I made a booking and I noticed that I picked the wrong date, I then changed the date and had to pay R1511.96 to change the date which I then payed as this was my fault. But I used that voucher of R6176.00 to pay the R1511.96 thinking that I will still have MY R4664.04 left on the VOUCHER which is mine... but no Mango took my entire voucher of R 6176.00 to pay for R1511.96. So basically they stole R4664.04 from me.... to top it all off I received a message from them stating that my flight was changed due to some schedule that changed. This is ridicules and I emailed them multiple time with no response...
