Pick ‘n Pay sold me old Aquafresh Mouth Wash

Hi I bought a Aquafresh mouth wash last week at Pick ‘n Pay on the 11/11/21 and I only saw today that the Expiration date was 10/08/21. I immediately asked for my money back when I got there because there was no time for me to wait for the floor manager “on lunch” and the manager already left.

I used the mouthwash twice and It left a bitter taste and my tongue felt quite sensitive and irritated after the usage but I wasn’t aware of the expiration date as yet and just this morning I saw the date and it came to my attention that that’s the main reason for the irritation and sensitivity on my tongue.
