Poor service

Pedros chicken Eyethu center (Soweto) Hi there My name is Sandra Laura Muendane ,on the 20 April satarday evening I ordered a meal that costed R140 and the delivery fee was R40 ,which I paid online via the Pedros chicken app and the money got debited from my bank account of which i authorised .,within 5 minutes the restaurant automatically cancelled my order as they said they don't do deliveries ,and shortly after that I received an sms notifying me that the order was cancelled and the refund process will take 5 days I waited since 22 until 26 April no money was refunded back to my account ,I called the restaurant to inform them that my money was not refunded then they said they will do a follow up and waited again this week ,today it's the 3rd of May my money has still not yet come in.I called the restaurant again today ,sent proof to the duty manager to inform him that I'm still waiting he claims that the boss at head office said the money was reversed to my account om Saturday 27 April and I must wait ,for how long must I continue waiting .This restaurant is ridiculous and doesn't value their customers I'm really ****ed off.
