As we have not handled the hassel-free returns process, we hate to say, but could you please list the address we told you in an invoice and send it? We appreciate your understanding and cooperation.
Our shop has not dealt with hassle-free returns process yet, so we're sorry to trouble you, but please enter the address which I told in the invoice and ship it. I'm sorry to bother you. Thank you in advance.
I am sorry but my system does not correspond to the "hassle-free returns process", so I would appreciate if you could return with writing down the announced address on a shipping document. Your cooperation would be appreciated.
