buyer won't answer questions about her address

[hibiscus_rose]

A buyer opened a request because they said their item hasn't arrived. 

This happened on 4/8/20

I've asked them  THREE TIMES  which address they use as there are two, one on Ebay and one on Paypal

I've also sent a receipt from auspost for sending it.   There isn't any tracking for a large letter unless insurance etc is specifically asked for -  They didn't.

What do I do now?

Which address did you send it to? If you used the one eBay supplied, chances are it's an old address.
