Appalling conduct of delivery agents.

I have always had top service from Checkers 60 delivery. I have been using the service since its inception and even whilst living abroad, I have used the service regularly to purchase items my family needed. More recently, while on holiday in SA, I have experienced very disappointing service from the drivers. In the last month I have had 4 deliveries, with 3 of them being awful. Two of the deliveries was from the same agent, and both times he made me feel very uneasy and uncomfortable. Both times he claimed to have delivered my items, but with joy even calling me to give him access to the complex. He even went as far as lying, saying that he had been parked outside my complex for over 30 minutes and had called several times. There was no evidence of either. He then yelled at me in the driveway of my complex and threatened me as I said I would have to report him. He even insulted me. Two weeks later he came to deliver again, and did the same thing, but this time over the phone, after I had called him, after he ‘miscalled’ me. I was so afraid to receive the order, I sent my husband out. I then laid a complaint against him. The next deliver guy about a week later did the same and in fact relayed the issue with the previous delivery guy. So it means that they have discussed this and have decided to deliberately treat customers like this. This guy also did not call me. He simply mis called twice. Unfortunately, we cannot open our complex gate for anyone, so I could not assume the that the miscalls are from the delivery agent. I called him back and he immediately started shouting at him for not opening the gate and then proceeded to relay what the previous agent had said. Again, as I felt extremely uneasy with his conduct, I had to send my husband out. I think it is appalling that the drivers can threaten customers at their home. We are trusting them with personal information, and when they feel free to threaten customers, it becomes scary to allow them into our personal space. My family that I usually order for when I’m abroad is my my mum, who is alone and my aunt who is often alone at home. Are these drivers to be trusted? Checkers needs to do some serious vetting and evaluations of their drivers or very soon they will have multiple law suits to contend with.
