Don't DARE make any mistakes when ordering from Nandos online apparently.

Nando's Online ordering: Clearly there's no room for error in making your order :) Ordered on the website from Nando's Rosebank, accidently left the wrong address in my order, but the address I was supposed to put in is 10 MINUTES AWAY FROM NANDOS ROSEBANK. Quickly called them to give the right address. It has now been almost 2 hours since I placed my order, call the call centre they can't help me. I call the driver he gave me such attitude and was so unprofessional when I was trying to be nice despite being hungry for almost 2 hours now. Is it that big of a deal to change a delivery address that adds an extra 5 minutes to the trip Nandos?
