Debonairs Avonwood Square bad customer service

I ordered a pizza on Saturday 16 November at Debonairs Avonwood Square in Cape town on the Debonairs app. The app showed that Avonwood was the closest to my location for delivery, so I submitted the order with them and they deducted my account. An hour after my order I received a call from Avonwood informing me that they would not be able to deliver to my location, so I asked why they deducted my account and why on the app it showed they can deliver. The manager just told she doesn't know and that they would rather process a refund with 48 hrs. Tuesday 19 November I called the store again asking about the refund and I spoke to another manager called Sam and he told me 48 would commence from Monday as a business day to Wednesday. Today ( Thursday 21 November) I called in the morning and spoke to a lady manager that told me she would called me back in 5 minutes and she never did. I again called this afternoon and got the Tuesday manager Sam who told me the lady manager had gone home and that he will call me back as well. That's when I told him that I've had enough of these "call you back" and that I will give him 20 minutes to call me back. He has then been dictating to me that I should hang up the phone and wait and not give him ultimatums of 20 minutes. He then called back to tell me I will receive my refund by Monday 25th because they entered 11 digits cell number on the system for the refund instead of 10.

This is really unacceptable, after 6 days I still haven't received my refund from this reputable franchise and the managers are plainly rude and unapologetic about their errors, instead they tell you what you should do and don't give you a chance to speak and share your frustrations. Now I find myself spending about the same money as the pizza on calls trying to get my refund and they never bothered to do a courtesy call to find out if I received my refund. Sam, the manager, blatantly told me he'd be wasting time in calling me because he has a lot of customers to call, MY WORD !!
