Mango_A|_s Booking Change *****

I want to change my Mango flight booking (previously I changed a flight with Mango, and it was easy and cost effective to do so). As per Mango's website, they say you choose your new flight, and pay a R280 admin fee - fair enough. <br> <br> However, things have changed - when you compare flight prices (new flight versus the price of the same flight when logged into their re-booking section) the latter price is ALOT higher. <br> <br> Mango, a) why is your pricing not consistent between the 2 platforms? b) your re-booking section of your website makes no mention that the flight prices are higher within the re-booking section of your website, when compared to booking a new flight and c) why the difference in flight prices, as you will be selling my original ticket at a higher price than I paid for it?<br>
