Dollarama review: No exchange or return policy ( 1 comment)

On oct. 15th, I purchased 2 packages of "c" batteries and 2 packages of "dd" batteries. When I was picking them up off the counter I realized that I mistakenly picked up 3 "c"'s and 1 "dd" package.
I thought I could put the pack of "c"'s back and just get another "dd".
According to the cashier "there are no exchanges or returns".
Seriously?
I get the policy and if I left the store. I was just picking them up to leave the store.
Can't customers make a mistakes? Maybe they were on the wrong hooks when I picked them up? Is there never a "one off"?
I wasn't bringing back food or I hadn't even left the store!
Very poor customer service.
I would love to hear the logic of this.
