Vitality Enquiry

I have been a Member of Discovery Vitality for over 10 Years and on Diamond Status, last year I some challenges and hence my vitality was cancelled in December 2014, I contacted the vitality offices end January 2015 as my circumstances changed and wanted to reinstated or reactivate my vitality and hence was given the run around, and told that Unfornutaley our systems reflect that your vitality was cancelled on 31 July 2014, this was incorrect as i was still on vitality and using the gym until December, I then further contacted Discovery Vitality on Facebook and I still have the communication on hand, and the person also concluded the same, I was disappointed but could do nothing, I then joined vitality again and was provided with a new Membership number, when i decided to Join Virgin Active on 9 August 2015, It was discovered that there is a record of my Gym visits and Membership until December, so I cannot understand why the call centre agents told me otherwise, Is your systems not linked? this has now costed me my vitality status due to missing out the 30 day period of not being on vitality all because the call centre and FB person did not check my records correctly.
