Pick n Pay bottles do not deliver the entire order after charging for it.

I ordered R4000 groceries on the Bottles app on Saturday 26 June. After 2 different drivers made a (late) delivery, I was still left with over R1000 of groceries not delivered. Their customer line is down, they do not respond to emails, and the so-called chat function on the app is also not working. I understand due to the pandemic they are under strain, but not delivering something I have paid for and there being no way to contact them is unacceptable. This experience has completely put me off Pick n Pay in general. Apparently they are unaware of the competitive consumer market and not bothered about losing customers.
