Poor service and customer support
I've made a transfer overseas at 6am on a Saturday expecting the recipient to receive this 2 minutes later (This is an option I've selected and paid for). 

It has been 60 hours since I've made the transfer and neither has the recipient received the money nor has it been returned to my account. 
According to support "unfortunately, some banks close early for the weekend on Friday, which means they stop processing transfer. If the money hasn't arrived yet, it will go through the next working day."

If funds  are not actually get transferred within 2 minutes between Friday - Sunday,  this should be clearly indicated. In saying that I have previously transferred money overseas on the weekend without any issues. It's now Monday,  and I have yet to receive the money or hear back from support.
