BAD CUSTOMET SERVICE

I purchase on the Pick n Pay ASAP app every Friday at 10am for the office open bar and do office groceries at Pick n Pay, and I've been doing them for 10 years now. On the 28th of March, I tried ordering on the PNPASAP, and it would open, and I had to update. I updated the app and made myr; the order was delivered. HOWEVER, RECEIPT OF THE PURCHASE HAS NOT BEEN SHOWING ON THE ORDER HISTORY. I'VE BEEN CALLING PICK N PAY FOR THIS SINCE 28TH APRIL REGARDING THIS ISSUE. all i need is the receipt because it was a corporate purchase on a corporate credit card. To this day there hasn't been any resolution or receipt sent by Pick n Pay to me, and this money was deducted from my salary because there's no proof that I did purchase the things. THE PNP ASAP CONSULTANTS HAVE BEEN ESCALATING THE ISSUE SINCE APRIL .All they tell me is they see the transaction, but they can't send me the receipt. The receipt can't be sent because I updated the app on the 28th of March, which baffles me. I can see all the other order history made prior to the 28th of March and after the 28th of March, but I was told the invoice will not appear because I have the new app. I'm exhausted from calling Pick n Pay today. It was my last call day. I've been calling Pick n Pay since APRIL, and no help. The one consultant said I should go to the Pick n Pay store. I did that, and I was sent back because they can't help with a PNPASAP purchase. PICKNPAYASAP. CUSTOMER CARE IS FULL OF *********** CONSULTANTS WHO KNOW NOTHING ABOUT THEIR PRODUCT. THEY HAVE BEEN ESCALATING TO GIVE ME MY RECEIPT FOR TWO MONTHS NOW A RECEIPT THAT THEIR SYSTEM DID NOT SEND TO ME !!!PATHETIC SERVICE
