Defamation of character

I have visited edgars in gateway mall today. I have purchased a shoe and a sissy boy jean this morning. I have been at the mall from around 9. I went back into edgars at around 3.30pm to look for dresses and tried on 3 dresses and another size of the exact same sissy boy jean as I did not try on the jean that i have purchased in the morning. Somehow my error the two jeans got mixed up when I went to try on the jean so I hanged back the wrong jean which did not have a tag so when I walked out the shop the sensor beeped. I was called aside by the security and he went to check footage. I waited in there security room and I was absolutely offended by the way the store manager Rajesh and another lady which accompanied him treated me and addressed the situation. It was an unintentional error I am only human. This error of mine did not cause any loss to the company. Their footage clearly shows them that I have hung back all the items that I have tried including the jeans(which was the one I paid for) but I was still treated like a *****. I am not stupid to leave a huge tag on my garment and walk out I would obviously check or remove it if I was a *****. Kindly address this matter with your staff as this is unacceptable behaviour for such a well known company this will definately cause a major loss of clients unfortunately undoubtedly you guys have lost yet another client due to your poor customer service. I will definately take this up as I do not appreciate the manner in which the situation was addressed once I get feedback from your store and ***** department.
