Poor customer care Pick n Pay Midlands Liberty Mall

I had a disappointing shopping experience at Pick n Pay Liberty Mall. On 2 May I was in the shop and saw that a Raka wine was available at a very good price to Pick n Pay Wine Club members. There was a poster in the wine department advertising wine club membership at no cost by the simple expedient of sending an sms to a given number. With the help of the wine department assistant I sent off the sms and immediately received confirmation of my membership. I happily took my wine and smart shopper card to the till only to be told that my card was not reflecting my wine club membership and therefore I had to pay full price. I went I went to the Customer Care counter in the expectation of some sort of override to be met by a somewhat disinterested lady who merely said I could not have the discount until my wine club membership reflected on my card (despite my confirmation sms). I do not live near Pietermaritzburg so it is not a question of simply popping in on another day. I felt badly treated and certainly not encouraged to shop in that store again.
