brand new in box and sealed. couldn't ask for a better purchase

Top FitBit Versa 4, a very good condition, with the possibility to extend the bracelet, the installation is easy to do, there are a few additional functions provided free of charge for 6 months, this has not yet been activated by me because I am unsure whether a cancellation is automatic or whether I have to take action. A very good device at a very good price

It's in perfect condition, it's as if I bought it new. I am very happy with it.

Watch ordered on 15 December, received on 22 December (Fine). But on 1 January, the watch no longer lights up (or the screen no longer works). Even when connecting the charger, no reaction. The last straw is asking the customer to disconnect his account before being repaired. How do you disconnect your account if nothing appears on the screen? ???? I'm extremely upset, especially as my previous purchases went well. So, what is your solution to my problem?
