Nandos Boskruin Has Disappointed Me!

This is so disappointing to type... on the 24th January 2020 i placed a order on the app, which never works and i actually should of known better. Nevertheless i placed my order and paid R333.00 online but never got a confirmation sms. I then emailed the branch and told them my order and sent a screenshot of of my payment. My food was delivered and the driver told me to pay, i said no i paid on the app already so he says that the Boskruin store told him to take the credit card machine and i must pay, i tried to contact the Boskruin Nandos but the phone just rang and rang. He was scared they were going to take the money from him if he didnt come back with it and ASSURED ME that a refund would be done, so i paid, again, but this time R338.00. I then went to the store on the 27th January and spoke to Patricia who was actually very nice and took my receipts and said i had to email through my banking details which i did as soon as i got home. Since then, iv heard nothing, no replies to my emails - just nothing! I dont know why I, as the customer, have to chase after YOU for my refund. No one will care, but i actually havnt supported your branch since January and i wont ever again if this is the service that you provide. Even if this isnt the stores fault and its at headoffice then you need to train your staff to pick up the phone and COMM-UNI-CATE that there is a problem, and i am certainly not driving up and down to Nandos Boskruin to figure out a problem you should be solving.
