Appalling service received from Debonairs

We place an order today at 18:05 and was told it will be delivered in 30 minutes. I called about 19:00 to be told it's on its way. I called at 19:15 to be told it's on its way at which point I asked for the manage to call me. Nozipho the lady that I was told was the manage was in fact not and couldnt even speak English properly, it took so long for her to take my no. Down and then another lady calls and says he got a message for her to call me. So now I had to explain everything again to her and then she says she will find out and get back to me so my question to her was why didnt Nozipho tell her the reason I asked for the manager to call me? Yet again another person that can't speak English properly.... Why let them be customer facing if English is a problem. This is not the first time that this has happened but now this is unacceptable. It's 19:45 and still no pizza and still no call.... If you guys are busy why not make a call to the customer and say it will be delayed instead of the customer making so many calls finding out what happened to 30 minutes... I want an answer as now I have to order from somewhere else and the family is just sitting here hungry. So Cindy calls me now to tell me the delivery bike is stuck... OK so why didn't the driver call and why didn't they call the driver when I first called to find out instead of just saying its on the way. So serious changes need to be made to that store. If was the owner I would be ashamed of the pathetic service and maybe you should be more involved in the service delivery of this store.
