Frustrated

I had a mambership with Virgin active three years back and my account was always update till I decide to cancelation, before cancelation I have it was confirmed that my account was update and that there is no any outstanding balance. One of the Agent call after 5 or 6 month and tell me that my account was owing one month and I refer her to ckeck with finance department as they confirm the account was update during cancelation. 3 down the line I receive SMS that I have been handed to Legal attorneys. I have contacted Virgin active finance to send me statement as it was confirmed that the account was update before cancelation but they still can't send me even though they still have my Email address but they are quick to send my information to Legal attorneys without even consulting me.
