Pathetic customer service

We recently went to McDonald's in Cornubia in Durban , my family and I were starving and decided that McDonald's is a quick and easy meal to get. We went in and paid with card for our meal , the cashier made us wait more than 7mins for the payment to process the time was 9.17 am and then the cashier started to walk outside waving the machine around in the air 😅... we finally received a message on our phone at 9.42am that the money for the meal was taken out of our account. At 9.46am the cashier tells us that payment was unsuccessful although the money came out of our account saying it will reverse in 24hrs ... we call the manager to query , he then called another manager. He told us if it does not reverse we must get a bank statement and come back... the other cashier went to the back and remove her name tag when we asked for her name. We stood there quering how come it was unsuccessful but money was out of our account and why must we go through the inconvenience of everything. We were very disappointed with McDonald's and there staff. We left McDonald's and got our meal at another take out.
