Cancelling Gym Membership

I got an Email and a call on 11 April 2016 my Gym membership was cancelled as I underutilised it in Feb. (I had membership from 2001 under correction). I called the Call in and logged a call to complain about this with the below information at 11/04/2016 16:30 and when I asked to speak to TM I was told there is no one there. I called again today 12/04/2016 and logged this complaint at 10:58 Ref no: ***. I do not recall any email saying I am underutilised for Feb 2016 (I have had before).I was also sick in Feb and struggling with Asthmatic Bronchitis that the dr booked me off (I emailed a dr note to them). I called Vitality department on 29/30 March and spoke to a man that confirm that my Gym visits are all in order and my gym membership is active that there are no problems. I called back 12/04/2016 12:31 to speak to a TM to get this matter sorted out and I was told they can't get hold of a TM and the call cut after holding for an extremely long time! With Customer expectations there is NONE, I am so disappointed in how this is handled and even why I was cancelled in the first place. Now they want R1 500 joining fee & monthly fee from me to activate Gym membership again!
