Incorrect orders/ bad service

I am a regular customer at their Tygermanor branch. 3 times in the last month the drive through person has gotten my order wrong. Twice now I have swiped for the wrong amount. The second last time they told me the payment was canceled. I didn't get a reverse sms from my bank so I asked McDonald's to please check if it did indeed decline. 5 days later I am still short on cash and no answer from them. Their management clearly doesn't care about customer service and no one on their side knows who I am supposed to talk to. Their refund policy is ridiculous considering that it's THEIR fault in the first place for not listening correctly. 3 times. I want an apology for bad service and an answer as to where my money is.
