Poor Store Management - 14th Ave Roodepoort

over the last 18 months i have had to go to the customer services counter many times as the prices on the shelf differed from those those I paid. On most of those occasions I asked to speak to the store manager. About 2 weeks ago, I had the same problem and spoke to manager Boetie at the 14th Avenue, Constantia Kloof store; he promised to get some one from Head Office to call me; I am still waiting. Today, I had the same issue: I was overcharged by R35 on a R45 item I again asked to see a manager; and a very junior gentleman came to assist me. I asked for someone senior, eventually after waiting for 25 minutes for them to grace me with their presence, Richardt (2IC for the store) and Karen eventually showed up. I asked them to give me a regional managers telephone number and they refused. Whilst I was there two other customers complained about the same thing. Hyperama cannot get a simple thing right - changing the prices on the shelf when either new stock arrives or when there are specials. Totally *********** and lazy management.
