For now I will cost the money of the shipment, since if I have been returned home for not having collected the package them there, and now I have to resend ....At least they have taken care to look at the certified document and tell me that the error is not mine.In what I do not agree is that they only reply to the mails once a day or if they are interested, thanks to this attitude the process can be extended months.I proposed that they send me the defective scales to replace them myself, but they have not wanted .... a bad experience with REVISOR.
