Hi I am an Amazon customer service staff member and have some concerns about your recent purchase.
Sure. What are your concerns?
You over paid. 
How much was my overpayment for?
It was for $70.
Okay, how do I get my money back.
You can give me your payment details for the credit back.
You should have that information.
We only have the last four numbers of your credit card.
What item is this in reference to? I seem to have forgot.
I don't have that detail, only that there is a refund to you of $70. 
I think that you might have the wrong number.
If you don't want the rebate we can just keep it for you.
I thought I was getting a refund, not a rebate.
It is a refund of a rebate which was over paid by you by mistake.
I'm sorry I'm my young child is causing a commotion and I have to attend to him.
If you just let me know your card information I can get that refund to you asap.
I have to go. Please give me your contact info and I will call.
It sounds like you need that extra money back.
I didn't get your name. Who am I speaking to?
I'm Norman Paul. How do you spell your name?
You should know that allready. You called me.
Jim Lee
