Clicks kingsburgh warning to the public and elderly beware of this store!!!!

So it's happened to me twice, my mother on numerous occasions, when with me as well and today it happened again and another women in the que said it happens to her often as well and it unacceptable and needs a thorough investigation! On every occasion they double scan products and then when caught out the cashier and supervisor gets extremely ****y! Trying to make out like it isn't an issue! If this had happened once it wouldn't be an issue by rectifying the problem immediately and not letting it happen again but it continues to happen with no repercussions what so ever and it's starting to look more and more suspicious each time! Im disgusted in the staffs attitude at the store as well with handling issues which just stinks of guilt of wrong doing!!! Your store is a disgrace and I will not enter it ever again. Rather give dischem my business going forward! How many others and elderly have they caught out with their instore little **** to date that havent picked up on it?!!! Its absolutely disgusting that you allow this to happen so often! Surely on cash ups and monthly stock takes you pick up on incorrect stock levels and cash flow?!!! This isn't monopoly money that you dealing with! You are playing with people's livelihoods! You should be ashamed!!!!!! Furthermore at the teller there is nothing to display the amount owing. You just get told what needs to be paid! If this doesn't sound suspicious to you then I would question your integrity!
