Angry customer

I made an order on the 6 of January paid online when the delivery guy come to deliver he said that I didn't pay the full amount he refused to give me my order. I called the store Canterbury the lady was unwilling to assist she said they is nothing they can do I have to pay. I paid and I escalated to nandos the fabebook team and they said they will get back to me within the next 72 hours. I got reference number is CAS 887539 K0V0Q0 after I received a call from someone from the store how ever the person did not assist also telling me the same thing acting as I am stupid I can report something that did not happen today is the 22th no is going anything I should be compensated. What a terrible service a customer must be the one running around trying to get hold of them, no one is willing to assist.
