Vivomove HR doesn't pair and connect with Phone

Vivomove HR doesn't pair and connect with Samsung S7 now. The first day it did. Not anymore.

I followed all the steps on Garmin connect app.

Vivomove HR = with phone.
Samsung Galaxy S7 'see' Vivomove HR but pairing is unsuccessful.

Where is the service station in Pretoria RSA? 

OR 

Should I send it back to Takelot.com?
