Disappointing

Utterly disappointed with the customer service displayed by Mr Price Phoenix Plaza, Durban, KZN. I understand fully that it is the festive season and everyone is busy but I sadly regret shopping at this store. Having followed a queue for 20-25 minutes to exchange a size, I was told that I should not have followed the queue in the first place, I should have went straight to the teller, dropped off my goods for return and then proceed to find my replacement. I was a little annoyed by the lack of info given to me by the security but went to find my size anyway. To my dismay, the store did not have the size that I wanted so I went back to the teller and told her that unfortunately you guys don't have a bigger size, can I please return this for credit? To which she rep**** that I needed to follow the queue all over again, that too in front of another customer making me feel like a complete idiot. Id have to stand in a queue for another 30 minutes?! Surely there could've been a better way to manage that? As a courteous customer I followed the queue in the first place out of respect for the other customers before me, just to be told that it was umecessary. Despite that, the sheer inconsideration to be instructed to stand in line again? I was shocked, I just asked for my packet and walked out. I couldn't believe the level of inconsideration.
