Real Canadian Superstore review: Employee

I was in store on Jan 23/22 around 9pm at checkout.
I was at at the self-checkout side next to the bread section. My husband and I bought a Butcher's Choice Sausage advertised for $9.99 (for optimum member price). But when we scanned the product on the machine it rung in as regular price $11.99. We flagged a Filipino lady (Connie) over to show her that the pricing is wrong and showed her what it shows on the app. She quickly said oh its because it has to be the same flavour as shown (mild Italian flavour). I told her that all the different flavours are in the fridge area and it was labeled as the price stated in the flyer. She kept saying its not and wouldn't listen. Then this older Filipino worker came over (she was the supervisor) and Connie and her kept talking in their own language in front of us and said again to us in English that the sale only applies to the flavour shown on the flyer. I got so frustrated and asked her if she can get someone to go back there and have a look because it was clearly the store's fault for having mislabeled. She calls a worker over (she was African) and she took the sausage and walked back to check the price. About 5 minutes later she calls that Connie lady on the walkie talkie and I could clearly hear her say "oh its in there? ok". So the worker came back to pass the sausage back to connie and she took the sausage and went to one of the register on the opposite side.. pretends to scan the package and then walks back to us and said "sorry, its not part of the sale". She literally lied to cover up her mistake. My husband got so fed up at point that he ran to the back to take a picture of the fridge area for evidence.
When he came back with the picture she still wouldn't give us the discount and she brushed us off so my husband suggested that we go customer service instead. So we had to wheel our whole cart of groceries to the other side of the store and line up at customer service. I told the guy what had happened and I said Connie refused to correct the pricing mistake. He then pages her on the intercom (which she never responded). Then 10 minutes later the other filipino lady from early (who is the supervisor) comes over and pretends nothings happened and acted like she didn't know anything about it. At the end the guy at customer service was kind enough to correct the pricing for us and he was very helpful and rung up the remaining of our groceries. Overall I just want to make you aware that you have some dishonest and incompetent employees working there. The fact that she lied and didn't even apologize is so unethical. The whole checkout process took us about half hour. If you need more info... I have pictures of the employee Connie, and the flyer which showed the advertised price and also a picture of the sign in the store where all the different flavours of the sausages were put together.
