Avoid Pick n Pay when you are pregnant

I went shopping at Pick n pay Evaton Mall and their customer service is disgusting. After I had conducted my shopping and about to exit the store the staff at the exit refused to let me leave with the trolley to my car parked in the premises. He boldly told me that their new trolleys do not leave the store. It being month end I had purchased a significantly large amount of groceries. The staff refusef to help me carry the groceries to my car even though they could see that I'm heavily pregnant and even after I communicated that I'm 8 months pregnant anf it would be hard and possibly fatal for me to carry those groceries on my own . I had to carry all those groceries on my own. They have no regard for customers at all.
