Online order messed up numerous times and still not sorted

'n Placed an order with Pick n Pay ( ********** 646) on Monday 11 February and selected a R90 timeslot for 10h00-11h00 delivery on Tuesday 12 February to the value of R4 524.74 . My delivery arrived at 12h00 soaking wet. The sugar, boxes of oats, cappucino etc. was drenched in water. I then rejected the entire order as I can not work with sugar thats lumpy and 40kg of oats that is wet. I phoned the call centre (and had to hold for 15minutes!!!!) and asked for a new order to be delivered on Wednesday. Nothing happened and on Thursday 14 February I phoned the call centre again about my order. I held for 15 minutes (again!) whilst the lady tried to sort out something with the logistics manager. My order was delivered around 15h00 the same day but COMPLETELY wrong. There are so many items outstanding and I received cooldrink I never ordered. On Friday I sent a request online to be contacted urgently and nothing happened. I then phoned the call centre again and spoke to Fanele who promised to redeliver my order on Monday 18 February between 10h00 and 11h00. Yet again NO DELIVERY. I then phoned the call centre again (will Pick n Pay pay my phone bill at the end of the month???????) and spoke to Nosiphiwe that promised to phone me back. Guess what...No call! I am BEYOND frustrated. I phoned the call centre just now again and spoke to a guy that made me hold. When he started talking after holding on forever the line cut and he didn't even bother to phone back! I do not know what to do... Pick n Pay online is the most USELESS bunch of people I have ever come across. Just give my money back please...
