Porcelain dishes promotion at Pick & Pay - a total fiasco!

Pick & Pay recently had a promotion involving porcelain dishes, for which one collected stamps - 1 stamp for each R100 shopping., Without going into details, ( I am happy to if necessary) I was extremely dissatisfied with the fact that the store, after running out of stock, promised to call me to advise when the stock arrived. Not only did I not receive a phone call, but I only received my dish after 7(!) visits to the store. Promises and undertakings were not kept; communication with customers was scant and unreliable; the attitude of the staff was dismissive and unhelpful. And this after spending thousands of Rands at Pick & Pay to collect the required number of stamps! What a disappointment!
