Samsung S20+ defect

Bought a new Samsung S20+ on contract 3 days ago and received a watch Active 2 with the phone (Cell C promised that the watch is Cell C LTE enabled - in which it is not). Yesterday my S20+ switched off and couldn't restart as there is fault with the S20's hardware. Returned my phone to Cell C Waterstone, and was told that I need to return my watch also as it was sold as a package! This afer I drove over Cape Town to collect the watch at another branch. I paid for a flagship model and got junk. Wasted time and data to set-up phone.
