Bundle scam

My phone got hacked because xfinities security [Edited: "Language"] .  I had to change my number and bought a new phone.  Was told it would be cheaper to get the bundle with the samsung watch . I told the girl I didn't want it but she swore it would only be 67.72 a month.. come to find out I'm getting charged 11 a month for the watch for 36 months 399..99.and $10 access fee.I didn't even want the watch. The phone wasn't any cheaper either. Where is the discount on the bundle. I was fraudulently sold this watch and I dont want it. What can I do?
