Extremely unhappy with Virgin Active

I lost my job through a retrenchment in 2023. I managed to stay afloat on the club membership until I could not anymore. I cancelled my membership with Virgin Active in December 2024. I am writing this in March 2025 and I am still being debitted and getting calls that my membership is owing. Wow!!! Cancelling this membership was the hardest thing to do. I went into the Glen Austin club and canceled for me. I was told that the system did not have a way of accessing my husband and child's memberships and I must come back with ID numbers. I went back a week later with the ID numbers. This time I was informed that my husband needed to come and cancel the membership himself. The lady refused to call my husband so that he could confirm the cancellation. I was the fee payer for the whole family. After I insisted that he could be accessed via the phone, he was then called. His cancellation was confirmed, so I thought. A month later he and my daughter are getting debt calls from Virgin Active. Now, today I also received a call that I owe a membership amount. Could you please clarify the steps needed to cancel this membership? This is after I had been a memeber for over 20 years.
