badly treated n insulted

On the 4th June I went to the store to deposit money then I saw my neighbour who always ***** at the shop I told the security guard to look at the guy carefully as it was not safe for me to tell the guard that the guy was a shoplifter. I forgot the money at home when I came back the Guard was tell his collegues n customers that I was a shoplifter, I went to the managers office to report him he was called n he shouted that I'm a ***** I came with my husband to *****. I blame myself why was I doing someones job who didn't care abt the loss of the company they promised to contact me which they never did I was so humiliated don't think I will ever step my feet. On that store again
