My family sent me a parcel and it never arrived. Got a letter to pay customs even though it was a gift (ok whatever) but I have no way of paying. My wife has an Spanish NIE number but I do not. I cannot pay online and cannot register to pay online with no NIE. It said you can get information at the post office. I went and they did not know what to do and sent me to tax building. Tax building found my item but could not help and gave me an email. Had no response from the company after emailing. I have no way of paying this charge its crazy and I cannot contact this company as they have made it extremely difficult. If posting to Spain from UK ensure the recipient has an NIE. Reading other reviews it seems that Correos are pretty awful so good luck if you use them avoid if you can!
