Mr D App - No payment options working

Tried to order food from the app and the app declined my card a number of times. Decided I would try the EFT method and the only option they accept is i-Pay, which has so many generics it’s difficult to even find the correct app. Then I decided I’d use the “cash” method, and leave a note asking them to please bring a card machine when they deliver, and am then notified that they don’t carry card machines. So irritating and so not worth using.
