R59 earings misunderstanding.

On the 24th August midday I was at woolworths with my mother and my three year old son, I decided to buy earing for my daughter took the earing went to show my mother so she could confirm if they were appropriate for my daughter to wear in school, after showing her I gave the earings to my son to hold as her was sitting on the trolley.I then continued talking to the lady I had an appointment with as my mum was paying didn't even realize the earing I had given to my son were not paid for, upon my exit I saw the earings on the trolley and I put them in the plastic I had with me and walked out that when the alarm went off and were my mother then told me she hadn't paid for them. To my suprise I was then told I had ****** the earings the minute I took them off the rank I asked them to please check the other cameras and they refused the security lady told me I must just agree cause if I keep lying things will be worse for me. I tried to explain but I was labeled a **** and was given a form to sign that I would never enter their stores again. I am truly disappointed cause woolworths is a store that I love and there are essential things I buy there every month. I don't know what to do cause now I'm blocked from using their stores for something I didn't do. I just needed them to check the other cameras so they could see that it wasn't my intention to ***** the earings I honestly thought my mother had paid for them when I took them from the trolley. 😩😩
