I am currently in Brazil for FIFA and going to France from here straight. I am back in Dubai on 22 July.
Honestly you should clear these matters at the time you get bookings as we could then change contract and forwarders to settle this as per our desire. Changing payment terms as per the situation is not something we ever propose to anyone and better to handle that much business that you are comfortable to handle as we are ok to accept.
I cannot look into these payments till end of next week and really do not like such situations
