Refund Order No DFD***2

Been using Mr D for a while now and just ordered 2 pizzas from Romans, order was declined due to the restaurant not accepting my order. Got a message to say my money will be refunded into my account but obviously no money came back into my account. Called Mr D, where I was told unfortunately refunds take 2-3 days & because its weekend my money will only reflect on Tuesday and that I should place another order and pay again. My point being, what if the next order gets declined again, do I have to wait until Tuesday for the rest of my money??? This is absolutely absurd & unacceptable & I will never ever order from Mr D again or even recommend their services. DISAPPOINTED!!!!!!
