Return problem

Hello, I initiated a return of my Order #2365833NA , and the return request was accepted: return request # 870E712945493. I sent it via registered mail to the exact addres you gave me: TRIANGL RETURNS Incheonweg 7 1437EK Rozenburg The Netherlands I went to check if the package has arrived with the tracking number I was given and they say that the addres is incomplete and they are trying to deliver it !! I'm really worried the package got lost in transit ! I already sent you the proof of postage in another email but never got an answer from you since...I'm attaching it here again. I really hope that you have an insurance for these cases in order to refund your clients: I followed your exact instructions for the return and also used registered mail, I did my part, and it would be poor customer service not to refund my order. Please help,Best regards, Cécilia
