Drivers

I'm Saturday evening I ordered a pizza which arrived 25min before the expected time on the app. My girlfriend was on her way back after going to draw cash but the driver insisted to get paid he couldn't wait. I totally understand I made a mistake and to make him feel better I asked him if he would be cool to keep my iPad as he couldn't wait 10min for my girlfriend to come back. He said fine and he would come back at 09h00 Sunday morning to bring my iPad back and collect the r90.00 for the order I had placed, I felt bad as I made the mistake and didn't want him to think I wouldn't pay him. Since Saturday their call centre has been giving me the run around about their driver and he hasn't returned with my iPad. They've done nothing and I'm been transferred from person to person everyday. I think the driver sold it basically. Hope they can help me asap as I've had to report it ******.
