Markham @Dobsonvill Mall. Not pleased

Bought pants yesterday tagged 599.00 but on the receipt I was charged 650 😑... went in today to enquire about the over price charge, and the guy told me it was a price changed and I was meant to pay 650, why weren't the tags updated or something? Now im returning the pants and I'm made to wait for my refund 😏😏😏 definitely not happy about this.
