Unsatisfactory service

Your kfc Heidelberg cbd outlet is serving nothing but dissatisfaction always.yesterday as always I asked what they have on the menu becoz 90% of the time they're always out of products.they said they have burgers and wings only(10 left).I ordered a colonel burger and dunked wings. Order comes out wings are only 6 and they ddnt dunk them.they replaced the 4 with a piece of meat they said they don't have initially. And all staff attitudes really make you feel bad for stepping in there.i don't know the policy of opening and closing times but it says on the door they close at 9pm but they shut the doors at 20:38.this has become the norm at that outlet.theyre selling out of stock always.
