Returning my router

Hi,

I requested the termination (or rather, non-renewal) of my contract for the 14th of February. I received an email confirming that the cancelation was registered, however I did not receive anty instruction regarding how to return the router I am using.

One of my concern is that I wish to leave Germany before the 14th (on the 1st, more specifically), and would like, therefore, to send the router a few weeks before. Note that, if need be, I could send the package from France, but I would rather take care of this as early as possible (i.e. before the end of January).

Note: my line number is the 06xx - 36xxxxxx

Thank you and have a great day,
Paul
