Welcome to our Community! @Sofia Cardoso 

I see on the track & trace that the package has been send to us on the 16th of January, I assume it is still on its way. As soon as it arrives, it can take up to six working days for the package to be processed in our system. The e-mail serves as a reminder, but you can ignore this as you have already sent the package back to us. Thank you! 

Ok thanks for your help.
