Terrible customer service and attitude

Very annoyed with Ackermans Eastgate. We paid for a whole lot of shopping at 21:00 (closing time) and while doing so my 1yr old son dropped his dummy on the floor. Right after exiting the store we realised we forgot to pick up the dummy and I went back at maybe 21:02 and they flat out refused to let me in to just go pick it up (even with other customers still busy paying). Instead they supposedly spent 20 minutes looking for it and still refused me access. So now I'm down a dummy and a strap (probably around R300). Certainly WONT be shopping there ever again. Tempted to lay a charge of THEFT as well.
