Unhappy client

I placed an order via Mr D food on 21 June I waited and waited I checked the app only to find out that they saying my order was unsuccessful I phoned pedro's was told that they did not have the garlic Portuguese roll and my order was rejected I asked them to prepare another one without those rolls and I had to drive out to go and pick it up when I got there they showed me that the order was rejected and today Mr D is telling me that the order was delivered to my adress and I was unavailable to pick it up they refunded 98 which I do not want they must just take every thing since that is the kind of service they offer I fail to understand what was the driver delivering if my order was rejected did they hoot did they phone they saying they communicated via the App so I paid R186 for a R139 meal they refund R94 is that how they make money from cheating the system. Very unhappy customers who wants nothing to do with this company
