Continuous billing on expired contracts-

My Contract cancelled and had expired but keeps on billing. I have had a year contract with virgin active in June to June 2025 which I have since advised in mid 2025 to discontinue which I was not able to afford as I was on Temporary disability leave. I have also advised to cancel my daughter’s membership. Since then I receive billings which I’m not sure where they come from. I was also told that a debit order was never implemented on my daughters account which I do not understand as the admin was done and all details where provided. I was constantly requested to pay the arrears for her. I have never received any systems from VA despite repeatedly asking. This is an inconvenience. I called the head office in September 2025 still o could not get a solution.
