Pathetic (non)service at Pick 'n Pay Mall of Africa

I received a Pick ‘n Pay gift voucher and went this morning (approx. 09h00) to Pick ‘n Pay at the Mall of Africa to use it. I took items 2x the value of the voucher. At the till, I was told that my gift voucher cannot be accepted because the “system is off-line”. The store manager told me that “this is not his problem”. Essentially, I was told by a Pick ‘n Pay store manager that he does not give a rat’s **** about me as a customer. After wasting 1.5 hours, I left the items at the till. The Pick ‘n Pay brand continues to be on a downward slide. Perhaps, when most of the customers finally abandon this brand, the company management will realise that perhaps not being able / willing to service customers is actually their problem.
