last year my wallet had been stolen and fraudulent cheques had been deposited into my bank, the bank had had taken responsibilty for most of the charges but had required me to pay for a portion of it, i do not believe i am responsible for any of it and it had been sent to a collection agency. it is also currently being investigated by the ombudsman of banking and investment services. i wanted to know what my options are and if the collection agency will sue me
