Shocking Service From Pick n Pay Kloof KZN

I have not been able to get Pick n Pay brand Low Fat Milk 1 litre for over a month - I shop there every few days and every time I ask the Manager they say they are waiting for stock and I should take another brand of which they only have 2 litres - how can PnP consistently not have their own brand ?? I always advise the Manager of other products that are out of stock and they have never taken my details and offered to call me when stocks arrive - what happened to the days when Managers cared ?
