Shoppers Drug Mart complaint: Double billed

I placed an online order October 20, 2021 which did not initially get billed to my credit card. I contacted PC to get my points which is when I found out my card didn’t get charged. I was told a manual transaction had to be completed to bill my card. However, they charged my credit card twice; November 4 and November 19 for $162.67. I have contacted Shoppers by email and by telephone. I was supposed to get a call back from a supervisor, and never did.

I keep getting told my card was not billed twice. Last email I was told again, the initial charges are a pre-authorization that is a placeholder on my card to ensure the necessary funds are available. As the the initial settlement did not go through, my card did not get billed. I know this. It like they don’t read the rest of my email. My card was billed twice in November when they did the manual calculation. I have sent copies of my credit card statement showing I was charged twice. I have sent 3 more emails in March and have received no response. TERRIBLE customer service.
