Get managers with willingness to help, empathy and most important to take ownership when a problem arises

There I am deciding to go to PicknPay due to the loving specials I normal get on selected range of wines so, I get there on the liquor section and I get four bottles of which all four of them are on special but one of them PicknPay decides to charge me the full price so luckily I picked it up as soon as I walked out because I just realised that the amount I am swiping for doesn't sense so, I go back and check if maybe it's not an error on my part and I realised with all the ads also confirming that I am not crazy then I go to the casher and by the way this not when all the problems started since I realised that there is a long line and sadly she had not support at all so I managed to keep calm only after 25 minutes she received support not from manager but another cashier even after the support the other casher took her to to releave the other so she can deal with my query until I said I seriously so she just left everything the went on a search for a manage. This when I got frustrated when the manage is focused on pushing the problem away from her by questioning the cashier on where are the other managers so, I then request to leave since she was rather prepared to find another manage then speak to me or help. Not even once she had the decency to even say sorry for making you wait... No customer service no care nothing which is actually sad... The cashier seriously should received support if so she would have handled the issue better I can on imagine what else she struggle with that day. Oh, before I forget I need to came back tomorrow with the bottle of wine and the receipt to get my refund. That's what I call services. Well done!!! PicknPay on your exceptional poor service
