Mobile App is Useless

So i live only 4 min away from the restaurant but busy day so ordered pizza, sides and drinks instead, because its SUPPOSED to be simpler and more convenient. Order a LARGE order on Mobile App. 40 min later get a call from the driver saying he is leaving now is it ok to ring the bell, um yes you can????? Please remember i live 4 minutes away, so 35min after the call the driver calls to say he is at the gate. Ok, so i go through 2 security gates and passed my 3 dogs. Get outside and do delivery guy??!!!??!!! Try to call driver and goes to voice mail 5 times, call restaurant, they dont call me back. Call them again, they cant get hold of driver. Turns out he went to the wrong address, a previos address i had been at 2 and a half months previously??!! Why!!?? No one can tell me. I call head office customer care before the pizza even arrived yesterday and they have still not called me back. Useless, the restaurant says its the App and head office says its the restaurant but no one cares enough to call me back. Payment was online and included tip, so they have no reason to get back to me! The order did eventually arrive 1hour after it left the restaurant that is 4 minutes away from my house. Everything was cold and rubbery and the drinks was warm. A complete disappointment!
