Discovery vitality go back on their word

My query has been going on since December 2014. I called discovery in December to change my medical aid from corporate to personal and thought this had been done only to find out in april 2015 that they never actioned the change. I had to rejoin discovery and lost my vitality benefits through no fault of mine. Virgin active said I had to pay another reactivation fee and I advised them that I wasn't prepared to do this. I got frustrated and wrote a complaint on hellopeter and someone called me from vitality. They resolved the query and said I did not have to repay a reactivation fee to virgin active. This morning I went to the gym and the manager at the gym said vitality had recanted and said that I did not qualify for reinstatement of my membership and had to rejoin and pay a reactivation fee. Really????!!!!! This is so disingenuous, and this is not how customers should be treated. To out right lie and go back on their word! I'm so disappointed. Something needs to be done about these people, you can't treat your customers like this. Its not right. This query has been ongoing since December 2014, its now November 2015 and still no resolution. And mind I pay my medical aid vitality
