Pick “n Pay deliveries totally UNRELIABLE - to be avoided

I had the same experience twice now. I ordered stuff online from Pick “n Pay and have chosen a time slot for delivery (8h00-10h00). I moved my appointments accordingly. Nothing happened - I waited in vain. After 10 I phoned their customer care, was told to stay on the line while they investigate - but was cut off. I waited a while hoping for a return call without success and then phoned again to try and make new arrangements, also without success. Since I had to leave I was forced to ask somebody else to wait for the parcel, hoping it will arrive - which it eventually did. Bad experience!! The online order system is totally unreliable. Not to be recommended.
