Complaint about Rude Given at Mc Donald's strydom park Malibongwe drive

I ordered a Meal at Mc Donald's Malibongwe drive in Randburg, the driver forgot my juice and I returned him with the food so that he can come back with fresh food together with the juice as I was not going to eat food without a drink and I was not going to take the food only as it was gonna be cold while waiting for the food to arrive... I spoke to a rude Given who told me it's not his problem that the driver forgot the drink. He then hang up the phone on me
