Mother won’t pay electric bills that are in my name

So, I moved out last month and asked my mother to put the electric back in her name. She never did but agreed to pay the bill when I sent it to her 3 weeks ago. The bill was due 5 days ago and silly me forgot to remove my bank account so now I’m out of $100. My main concern now is being responsible for paying the next bill since it’s in my name. I plan on terminating the services on Monday if I don’t hear back from her. If I can show proof that I moved last month will BGE still want me to pay?
