You would think a company this big could figure out an app

I have had this app for a while and have now purchased 12 large Mc Café coffees and have still not received any for free. More than half of the time that I open this app it tells me that they are having technical difficulties so they cant even find the store that I am sitting in the parking lot of, and not only that but there are never any deals as they say there will be. Figure this out McDonalds
