Treated Like a ******** at Store

Two weeks ago on 19 Feb after 3pm I went into the Ackermans store in Promenade mall. I politely asked the lady at the fitting room if I may use one of their rooms, and explained to her that I I think I lost my cell phone and would just like to pack out my bag to look for it, as it's quite a huge bag. She said yes I may, and that I must take a garment with me as well. I noticed that she wasn't very friendly when she answered me(facial expression). I went in searched my bag, but couldn't find my phone. And thanked as I left. However, as I was leaving the store, one of the staff members came running out the store after me and said the security needs to check my bag, his facial expression explained it all. I was furious because I immediately felt like a ********. I went back and they were all standing there looking at me like I stole something. And the security didn't check my bag either!!!<br> Why was I treated this way?? I felt highly offend, hence, I wont be supporting Ackermans Promenade Mall in future ever again. Upset customer.
