PNP ASAP ORDER SERVICE BAD

I am extremely frustrated by the PnP ASAP App service. I had to place an order 3 times today and everytime the order gets cancelled. i placed the first order at 09h00 as i had kids at home in the morning, by 12h30 it was not delivered but cancelled, i placed the order again around 12h00 , still the driver goes out but it gets cancelled. I left messages for the complex security to send him to my place when he gets to the gate but told he never came, the 3rd time i placed the order around 2pm as my kids were still without food and this time shared an alternative number with a note for the driver to call when he gets to the gate, this order was returned to the store, i called the driver who was rude to me and said there was no unit number and that he called me and number did not go through, i told him i have the phone in my hand been waiting for a call and he ad another driver will deliver it. This is really pathetic because this isnt the first time this happened, why do you this service if you don't intend to deliver or deliver ASAP?
