Rexall Drugstore

This is my first time to shop at Rexall Stroe at 350 Cresthaven Dr, Nepean and I assume I won't go to that store any more becuase of the extreamly bad experience of the customer service and the guy who told me that he is the manager of this store. This afternoon, I went to the store and bought a item. The origional price is $10.49 before tax with a big and clear 15% off tag at the bottom of this item. We took one and checked out. After we got back home, we reviewed the receipt and found we were charged the orgional price and 15% was not reflected on it. Maybe you think it is not a big deal while I beleive the sanner price accuracy is very important to each customer (especially for the customers who shopped there first time) and building the good repution for Rexall business. I jumped into my car and went back again to the same store. The sale assistant looked at the item and went to check the item price with a BIG and CLEAR 15% tag still on did not say anything and called a man who works here. That staff took us to the check out station and looked at the wrong price DID NOT say anything to us and in low voice told the previous assistant: the tag WAS NOT taken off eariler. At that moment I hope he can say at least a SORRY for their mistake and we need to come back and check. But he did NOT. He told me he will reture it and sell the item to me at the price with 15% off. That is ALL. I was very upset. I believe you can undstand I DO NOT Care about the 15% discount for a $10 item while I DO Care if you really value your customers like you posted on your website and social media. SO I asked him if they feel sorry about their mistake and if so they should pay for their mistake, not me. He said all he can do is selling this item with 15% discount to me. That's all. I asked in Canada, many companies sign the promise to customers that if because of their wrong price codes, customer bought the item (price less than $10), and they could get it for free. That staff said NO for us- Rexall. That is fake info on social media.
I understand maybe Rexall does NOT have that care and protection to customers while I need an apology, a serious apology from that staff. If like he said he is the manager of the Rexall store. I feel sooooo disappointed on it. As customer, I should not pay for his mistake, wasting our time driving back to store and doing the useless arguement. I will be waitng for the customer department to address my concerns.
