Barier to cancelling membership and amendments!!!

during the 2nd week of July 2015 i contacted the call centre in CT to cancell my and wfie's membership linked to own your life programme as i felt that the own ur life was becoming too expensive. i was already out of my contract period with Virgin and on a mth to mth basis. i was told that the call centre cannot process my request and had to go in person into the glenvista centre to cancel. i found percu**** with no valid reason being supp****. i then went on the 22 July to the gym and was then told my membership was canclled however because it is after the 20th i will still be debited. I was not happy but was told that i needed to take up with head office. i also requested for my wife's membership to be converted from liberty to cash 24 month contract. they said they could not assist with this as only head office can do this on the system as liberty membership must reflect as inactive first. i called the call centre today and was told they cannot refund me for the debit i needed to give them 20 days notice which i was not advised of by glenvista. also they cannot convert my wife's membership to cash as liberty still reflects active and i must follow up with liberty why it is not
