Can't do attitude and regid

I tried to exchange a dress for a smaller size at the Cradlestone Mall. They have all the excuses why they cannot help me and are only doing the bare minimum instead of trying to resolve the issue. I had to direct the Manager to their systems where they could get the information yet still they do the bare minimum not to assist me and only looked at their records from July and is not prepared to look further to get the information and help me. Absolutely shocking!!!!
