Debonaires Pizza Centurion Lifestyles Bad Service

I ordered a pizza along with a 1 litre coke zero, driver came to deliver just the pizza and forgot the coke, told me he'd be back soon with it. I called about 3 min later to ask them to change it to a regular coke (realised when i was checking the slip that it was the wrong coke ordered). Took quite a while firstly for someone to answer the phone and after answering i was told the driver parked his bike and ran away. I don't know how seriously debonaires takes customer service but i am ready to stop supporting them if this is how they treat their customers. I did my part (ordered early and paid what was due) and this is what i get. I hope this employee gets some sort of warning!!!
