PATHETIC SERVICE AND CUSTOMER SERVICE FROM MC DONALDS SA

I have been to Mc Donalds in the space of 3 days. Two seperate branches.

First incident occurred on Saturday 23 November at 2pm at the Florida North branch, I placed an order for 3 Desserts, 1 Kit Kat Mc Flurry, 1 Oreo Mc Flurry and 1 Strawberry Sundae. I wait for 30mins for this is to be prepared, upon asking where my order was, i was told that the people who ordered after me placed order for desserts, when i showed the cashier my order and told her it was a dessert order to, she advised that they do not have my slip and it was lost in the kitchen?

Second Incident occurred on Tuesday 26 November at the Mc Donalds Hillfox branch, order was placed for 3 big mac meals, 1 Mc Feast Spicey meal and 1 Mcfeast Meal, Upon returning home to feed my family, there was one burger short, which on my till slip is paid for. When i tried calling the store number, there was no answer, on Wednesday morning i contacted the store, again no answer and also no response back from the Customer Service department.

What type of service are we recieving from a Fast Food restaurant who is possibly in the top 10 in SA. I have pictures and slips to prove my review as well as case numbers from the incidents which i have logged .
