PnP ASAP - Dissapointing service !

Placed my order this morning at 8:18 on ASAP. Delivery confirmed to be 10:00 - 11:00, when I logged onto the app at 10:00, it was changed to delivery 12:00 - 13:00. When I logged know at 12:00 it was changed to 14:00- 15:00. When you phone the call center you hold 20 minutes just to get a "Sorry we are having difficulties with the app today." There is absolutely no client centricity, no service - you just have to be satisfied with a sorry. And when I asked why was I not notified of the changes, I received the same answer. If your app does not work, or cannot handle the volumes, disable it until you can deliver proper service.
