Loyalty department

i got a call several months back from loyalty department that said i was eligible for a smart watch and a security camera. I wasn’t interested but they persisted and assured me at least five times that it would not increase my bill one cent. So i agreed and they sent camera and watch. The camera worked for several weeks then quit. I spent a day on the phone to the loyalty dept.and he concluded I needed a new camera. I never received the camera. I was charged 10 dollars a month for the security,and 25 a month for the watch. So much for not one cent more. I then called to cancel the security plan, not an easy task in itself, took me two days being hung up on twice with no call back. I was told it would cost me 300 dollars to cancel my contract, which apparently you agree to if you use the product. I was under the impression it was for loyalty I was getting this camera and watch but it was just a sales plan. Very not happy and am looking for another provider for cell home phone and internet.
