Fed up customer

I have been using the Sixty60 app and most of the time struggle with delivery person. Some get to the address and some end up calling in to make sure they get it right. I even wrote to help desk to ask them to assign a driver fami**** with the area. Today my order got cancelled 😠 because someone didn’t get the address. I love convenience that’s why I use the app but I hate it when I get this kind of treatment. Why don’t they just cancel the app to this area(Kimberly Retswelele) if they can’t get competent drivers.
