Poor service

<p>I went to Pick n Pay, Kwa Thema this morning to do some grocery shopping. I had printed out some discount vouchers which expire today. When I got to the counter the till did not recognise the vouchers. I stood there for about 30 minutes, the what I would assume to be the Supervisor called the Head Office and the lady she spoke to was very rude, stating that the problem is at the main offices and there is nothing that can be done the vouchers will expire, my loss and hung up before I could speak to her. The Supervision called again and I spoke to a different person, who was a bit helpful. Why was I not informed via email/sms on this inconvenience? The employees from the Head Office must learn how to communicate with customers in a respective manner.</p> <p> </p> <p> </p>
