Bad service

Bad service experience from the store at the glen. I was there now to exchange and I had to wait more than 10min to be assisted. There was about 10 people behind the counter busy with their own work and not assisting me. In that crew was a supervisor. It's still early and quiet not busy but i waited for more then 10 min. They don't put their customers first and that's bad customer service. I'm so disappointed at them because I work with clients myself and we dont let a person wait 10min unnecessarily when there's people that can assist.
