Email checking please

Could you check the below email?

I'm sorry to keep you waiting.
I've been trying to find some other way to change my address, but I couldn't find any clear answer for this kind of issue.
If I pay the invoice that you've already sent, is it possible that you send the item to the address below and refund shipping cost?
<address>
If you can't, do you know any other way to change my address?
I am really sorry for bothering you.

Thank you in advance for your help.
