Mr Price security and staff sucks..canal walk

I went to Mr Price in Canal Walk to exchange some items. On arrival ti passed security and showed my bag in my hand where she gestured to go in, not checking my items. I went straight to the till points, from where the cashier asked me if I showed security as they supposed to mark it. She escorted me to the security from which the security denied it. I was so humiliated. Eventually I was helped by a cashier that had no idea how to do a return and the manager or supervisor had to assist twice. Totally unprofessional and totally embarrassing. I love shopping at Mr Price but won't go to Canal walk ever again.
