I didn't like the attitude! they didn't even return the money for the defective product at the expense of tourists, even the lenses, I opened them in the store without leaving, looked at them, they were defective, I told them to return the money, but unfortunately they refused and the product itself was taken away, I didn't even want to !! I advise you to return my money to my card back!decontamination is not a problem for me, but your arrogance and fraud are the limit!!
