Cancellation of Virgin Active Membership

Please note that I telephonically phoned Virgin Active that I will not renew my contract nor take up a month to month payment option and I was not allowed access to any of Virgin Active Facilities since my contract expired in 2017 meaning that I never used any of your facilities since the expiry date. Today, I received a notification my their lawyers that I am in arrears of 1521.92. I am requesting you again for the second to cancel the contract. I do not owe a cent to Virgin Active and such Virgin Active lawyers have no right be sending such notification. Membership No. *** ID Number: *** Regards Isaac
