I was caught by inspector, when I was going through the gates. he writen my name, surname and adress in his paper notebook, and said that underground will send me a letter with warning, fare or smth else. what would happen, if I won't pay the fare? i'm not planning to live in that adress for long time, and don't have money..

Credit/debit card number.

Today i get charged a tube penalty fare.In the fare ticket is correctly written my name, but incorrect my surname, birth date, and home adress. Also on it is correctly written my bank account number, from which they will collect fare. I have to pay the fare or i can just forget it? Thanks!
