Discovery Vitality is a *******

Can someone plz explain to me how discovery has managed to take complete advantage of its customers. We were told to migrate from momentum multiply to discovery vitality before 31 March 16 and we would qualify for the no activation fee special. My vitality ws activated in February bt now I am being told that I need to pay R1450 to activate my membership.. I hv not even received any of the Vitality cards I requested but Vitality has not failed to debit my account. This is truelly unacceptable, No mention of "You have to go to Virgin active before 31 march was mentioned anywhere in your communication to me/us, only that we need to be vitality activated ws noted. How do you rip people off by supplying incomplete information and then expecting them to pay for that? Im very disapointed!
