Bad attitude,lack of customer service,Not Impresse

Yesterday i bought 2real deals for R39.it was 18:13.i waited for more that 30min for my order and i went and ask cos No body was telling me anything.then i was told there is delay or misunderstanding.i went back again after 15 minutes and the guy apologized to me and said Precious was suppose to come and apologise cos she took my other Pizza and gave it to somebody and i said to the guy she didn't come to me and the guy told her Precious you owe the customer an apology she just looked at me as if am mad.i asked her and she gave me attitude and said cant you see i am helping other customers and my sister in law asked are we not customers also?i told her take the slip and give me my money and she said to the lady that she works with that give me the slip and i refund them. she dint even show that she was sorry after making me wait for an hour for my pizza. Then guy came to me with my Pizzas and tried to apologies and give the cold drink which i refused to take cos i felt the guy didn't do anything the person responsible it Precious. My question why you give my pizza to someone not tell me?why bad attitude when i ask about my order?why not apologise?why not treated like other custom
