How can a payment be 'unauthorized' if the buyer purchased of their own free will?

[ezseller]

A buyer purchased an item from me, requested a different mail to address and when recived posted positive feedback on the site that I have a store.

How can the sale be declared UNAUTHORIZED when they purchased, recieved even commented ?

I have second person just yesterday who purchased 2 items.

Today she writes that I withdrew money illegally and it was not authorized.

I have no access to her account.

She purchased from me.

I figure this one is crazy and refunded the money

BUT I do not get: UNAUTHORIZED?

they pay and what? Claim that we took the money? who is the theif? -e z seller

It could have been someone that stile the  credit card information and used it to buy something from you.

You co-operated by sending the item to a different address.

Call the police and lay charges - you have the scammer's address, let the police pay them a visit.

Or send the Postal inspectors - they're even nastier.
