you may have an samsung members update avaliable on the play store? typically their is a 'claim now' in the benefits section as mentioned.
however, the following URL will take you through to the claims page on the Web. Be aware you'll need to be able to provide proof of purchase and IMEI screenshot from your phone whilst you do this.
