Insulted by a security guard

I got insulted by a male security guard at the check out in Springs Avenue. He called me all sorts of names when he wanted a receipt at the door as I was about to go out the door. He couldn't find the items receipt in the shopping bag told him I probably forgot it by the cashier and he started calling me crazy and even insulted me about my mother. I went back to the cashier and found the receipt just next to the cashier's chair meaning I dropped it by mistake when I was packing the items I bought. What's sad is that the other female lady security guard was also not remorseful instead she was also against me. Things only got better when some guy intervened. I'm disgruntled by the treatment I got worse in my highly pregnant condition.
