Mc Donalds Observatory delivery service is pathetic!!!

this is the second time they get my order wrong and because its a bulk order at work i only notice that the order is wrong once i hand out the foods to everyone. 29 September i ordered and got a missing Big Mac Medium Meal Missing, a Medium Soda and 2 sauces Jalapeno sauces that was paid for missing in my order. I queried this and ended up having to ask my boss to physically go to Observatory MC and get my meal. This was unfortunate for me coz i needed to stay and extra hour after work because of this extra lunch i requested. I logged a complain with the call centre and got a incident number CAS41207-W5D5T9. They tried calling me the following day and moments after i was unable to answer the phone as i work in a call centre i get an SMS that the incident was resolved..Yes went and fetched my food myself..after i had to beg for extra time and had to work an extra hour on a friday! Same thing happened yesterday 13 October. This time when i placed the order i asked them to please get the order right and note to add my sauce. Again!!! the come with a missing medium Soda and the 2 x missing jalapeno sauce. Again i paid for something i didnt get. I really wasnt gona ask my boss for extra time and stay another friday late at work and just called the call centre to lay a complaint. I told them that i work in a call centre and cant take calls during working hours..Again!! i get a call same day get an SMS with incident number CAS 42142-G2G3P2. Yes nothing came from it and i feel ive been *****ed twice by this ppl...All they do is send and SMS and nothing comes from it.. This is theft it might just be sauce and a soda but i logged..the delivery man didnt come back with the correct stuff. do they expect me to go to MC myself every week when i order and get incorrect orders? I am so upset and disgusted by their lack of customer service.
