Multiply Tavel Desk ****!

I booked an Emirates flight through the Multiply Travel Desk. Due to Corona scare I have decided to delay my flight from March to June. Emirates has stated that there will be no change fees for flights as this global pandemic trashes all travel plans. Multiply Travel Desk however say "Total cost to process requested date change = R2336.44" I queried this saying the airline does not charge so why such a high fee, there answer is: "Please note that Emirates has waived the penalty charges however if there is any difference in fare and taxes, those will still be charged. So the difference that you will need to pay less the penalty fee is R1830.44 subject to availability." So they were still charging me a waivered penalty fee! Now there is a R500 difference in price. I worked out the price of my March ticket and that of the new June dates and with taxes for the same class of ticket (Flex) and it should cost me no more than R830? Yet I am being penalized by a division of the Health provider Momentum for a global health scare! Disgraceful! They are taking complete advantage of consumers when they should be the ones we turn to in this crisis! Disgusted, Marios
