McDonald's Delivery (McDelivery)- Extremely Poor Customer Service

I placed an online order for delivery on the 29/04/2019 at 10h10 for delivery at 12h30 to my work address . i paid online as well. I received a call from the designated branch McDonald's Lyttelton 18 minutes later to confirm my order. i then received a call again from the same designated branch 1 hour later telling me the my work address is out of range and i should call the call center ********** 623 to help me resolve this issue. i did this and the call center told me that they are going to cancel my order and refund my money into my bank account which will take 5 working days of which to me is unacceptable. According to my work address i am about 8 kilometers from the designated branch McDonald's Lyttelton and exactly 1.7 kilometers from another branch McDonald's Waterkloof. My Question then is if my work address was out of range why did they allow me to place an online order in the first place as my delivery address was visible then.

i spoke to the call center again and asked them to sort this out and asked to speak to the person in charge as i refuse to wait for 5 working days for my refund or they should then give me a voucher for the amount i paid for my non existent order for delivery but nothing happened thus far and i was promised by the call center agent they would get back to me.
