UberEat problem becomes the clients-Very unfair!

I placed an order via uber eats yesterday. Ubereats sent an automated message saying there was an issue with my order and I need to place it again. So I did that, except with a different restaurant the second time around as the original order was a buy 1 get 1 free which was no longer being promoted. After I place my second order with a different restaurant, the initial order and the second order got processed and I was forced to pay for both even though it was Ubereats fault..... How ridiculous??
