Venting about mom

As soon as I turned 18 my mom talked me into getting a cell phone & cable bill in my name. She promised she would pay them because I don’t have a job, I’m just a student. It’s been a few months now and the companies are now getting tired of giving us extensions because she never comes through with an payment. Now my credit is messed up and I barley had credit to begin with. Now I have to find a way to pay all that money back and suffer without service & WiFi. That’s not the point though, it’s the fact that my mom gave me her word and she let me down. I’m just so sad. If your under 18 please don’t let anyone put anything in your name. If it’s really necessary they’ll put it in their own name.
