Overcharged at till - ignored by managegent

Shopped at Pick n Pay Faerie Glen early Saturday morning 26 September 2015. Store was quiet and no pressure on cashier. Charged twice for a box of corn flakes - noticed this when perusing the till slip at home before discarding. Concerning to me because surely cashier would have heard the ring up tone record twice! An honest mistake - I think not! Reported the issue to management via their website. Have received no response whatsoever. This indicates to me that Pick n Pay management is not concerned about client service and ostensibly condones cashier dishonesty.<br> <br> Well done Pick n Pay, keeping quiet will only serve to cement my loss of faith in the company and its ethics (or lack thereof).
