Never ordering from ASAP again

Pick n pay asap. I ordered yesterday the 18/08. In my order was 2 x 2l full cream milk because it was on special. When my order had arrived the milks expiry date was for the 19/08. I emailed them got a ticket number ***. Haven't heard a word after that. No email no nothing. Am I supposed to drink 4l of milk in one day. I don't think so. If the milk is on special like that and you need to get rid of it then put on the app what the expiry is.
