Bottles App false same day delivery claim

I am highly frustrated and annoyed by the Bottles App service and its employees. I placed a grocery order today at around 3pm and received a call at 18h20 that unfortunately I wont receive my order today. Due to a high number of orders received on the App, they cannot get to my order as delivery drivers are offline.

I was assured by the app that my groceries were being prepared by Pick n Pay but now your employees are contacting me to let me know, no one is available to pick them up and deliver them. I don't understand how the The App can offers customers a same day delivery service, accept and process orders - creating the false illusion that groceries will be delivered when in reality this is all a fabricated lie. Your employee Bongani Bodezi had the audacity to rudely put me on hold and have me listen to background music while I was expressing my frustrations to him, then blame it on his touch screen phone. Bottles cannot contact clients 10 minutes before groceries stores are scheduled to close to inform them that their deliveries will only get to them the next day. Its incredibly inconsiderate and selfish especially during difficult times for many families. Food is a need....not an option. You jeopardize people's livelihood because your App and brand is so greedy, it takes on high numbers of orders when it doesn't have the capcity to carry out those orders. You advertised a same day delivery service to you customers, which is a false claim and misleading advertising, you need to correct this immediately. The only reason I use this App versus others is because of that guarentee of convenience - which you failed to deliver on. I've incurred bank charges paying for an order I did not recieve (regardless of the refund), I have been inconvenienced and thus can no longer cook supper due to a lack of ingredients and this incident had added to my emotional distress. I demand to be compensated for your incompetence and for this matter to be escalated to the relevant parties as a matter of urgency!
