Pick n Pay Bottles App worst customer service and delivery time!!!!

So I ordered on this app many times and had no issues thus far, used to be a regular buyer since the app came out! Yesterday i ordered to the value of R692.26 and did not receive all my items. After spending 8 min on the phone being transferred back and forth i finally hanged up and send an email to complain and request my items be delivered or refunded. So here im still waiting for emails going back and forth with ticket number extra... Today i received a discount coupon so i decided lets give it a go and see.... they can't possibly ***** up AGAIN. Keep in mind i do have Checkers 360, but decided to give Pick a Pay one more chance as they are very slow but assisting in my issue... So here i go and order AGAIN with my discount and the app deducted my money out of my account the delivery time is set for 16:00 - 17:00. WOW the moment the app send me to my order being processed... THE DELIVERY IS SET FOR 21.11.2021 TOMORROW 12:00 - 13:00!!!! Seriously i placed that order at 15:30 today 20.11.2021!!!! This is rediculous causing me to go to the nearest shop and buy the same goods spending more money then i would have! Causing me to now pay for the same goods twice!! After calling and spending all my airtime to HOLD for a call I ended up with no airtime and no customer support! No, I yet again need to send a mail complaining and hoping they will refund me and cancel my order as I already had to go and buy the goods. I'm so ****ed off at this service and this app I will NOT recommend ANYONE to use it as I will deactivate my account with them and spend the same fees on CHECKERS 360 Im sorry i never used to shop at Pick a pay, then the app came out and i actually started liking your products, but this is a ****ty service and for someone who spends 3 to 4 times a week money on your app and products im done!!!!!
