Bad service from PNPASAP

Good day. I don't consider myself a difficult customer and have all the patience in the world however, I am currently in a situation where i placed an order via PNPASAP like i have several times before. Today I encountered bad service which is placing me in a difficult situation. My order was placed and received on the app at 15:24 with an expected delivery time between 16:30 - 17:30 which i was okay with. I ordered Pampers for my baby which is I needed, is currently on special and also made used of the free delivery code to save on cost. Placing my order at 15:34 was sufficient time for my order to arrive before my babies nappies runs out. It is current 18:55 and the status of my order shows preparing your order since 17:23. I got worried as my orders never take this long and called the PNP Call Centre at 16:57 with *** and spoke to an agent Saaj who assured me that my order was placed before 16:30 and that I can expect my order today. I have tried calling the nearest PNP branch which is the N1 City to confirm whether my order is with their store on *** at 18:17, 18:29 and 18:35 to no avail. It is currently 18:53 and my order status has not changed. The delivery time currently reflects 08:15 - 08:45 on the app. I am now left with no choice to spend money that I did not budget for and buy nappies at normal price, using my fuel, stop my c****s and make it to the store and back before load shedding. I could use other delivery services however I have been loyal with PNPASAP and therefore am very disappointed in the service I have received today. Your assistance to resolve this matter swiftly will be highly appreciated.
