I have been going to pick n pay KENILWORTH CENTRE since the 23/01/15 for the special of ARIEL AUTO WASHING POWDER AT R49.90 PER 3KG.My rain check now has been renewed to 23/03/15 .I walked in yesterday 1/4/15 and was told by the customer services person that they had stock but it was sold out immediately.When I asked her why I was not contacted as my details was taken and written in a small black book(to contact me once the stock comes in) she told me that she cannot answer me on that.So who at PICK N PAY KENILWORTH HAS ANY ANSWERS FOR ME OR HOW LONG DO I STILL HAVE TO WAIT ?3 MONTHS OUT OF STOCK FOR A PICK N PAY IS ABSOLUTELY UNACCEPTABLE.
