Die besten Restaurants mit Doner restaurant Essen in Rülzheim

Last 3 orders totally messed up. Don't understand why? Sometimes the sauce is missing. Sometimes they're late and now I'm sitting and waiting for the delivery that was supposedly sent to the wrong address. When I asked, they said it would arrive soon. 30 minutes later still nothing. The woman on the phone doesn't understand German well and so do some others. What's wrong with the store???
