The buyer contacted me that one of the toy's optional parts arrived broken.
I sent a partial refund or an offer of returns.

And, from the breakage condition, considerable damage to cardboard can be considered during transport.
I requested a photo of cardboard.

But the buyer said there is no cardboard.
There was no reply as to whether there was damage to cardboard.

And the buyer said some refund amount is small.
The buyer requested an amount of $ 170 against the purchase price of $ 258.

The buyer made $ 170 for the reason that the item is not usable.
The buyer will not return the item though it said that the item will not be usable.

I told buyers to make some refund a little cheaper.
But buyers said would contact ebay.

This is a partial refund fraud.
