The buyer asked for return after 52 days (the listing accepts 14 days) after the item was delivered explaining that she actually gave a US address so that get around the Global shipping and import charges.
She was trying to return the item after she received it in Russia.
(She arranged it somehow with a third party).
The buyer claimed that I do not ship to Russia. I explained that I do via GSP. Then she threatened to leave a bad feedback if I disagree, and she did when I pointed to too long waiting period for returns.
