Failure to deliver

I normally do my 88 year old mom's shopping for her, but being full of flu I thought it best not to, so I ordered from PnP online. I ordered on Monday for delivery on Tuesday morning last week. Many items that I wanted were not available (their Asap delivery was even worse), and by Wednesday afternoon the thins had still not been delivered- really pathetic. They claimed that they had problems with availability of some items, but I suspect that They didn't deliver on Tuesday because it was a public holiday. Thanks for nothing, PnP. I've looked at the Checkers app and they have all the things my mom needs, so I will use them in future.
