Being misled again, very unhappy customer

Cebo was assisting me in converting form my Liberty benefits to Vitality & he said I must pay the joining fee which was R1225 & I paid at the end of April 2015 & he said they wont debit on the 1st of May, Surprisingly they tried to debit on the 4th May which came back as unpaid. This month they haven't debited & since from last month I don't have access to the gym, he said he will sort it out but he didn't, I called the call center & they said my membership is not authorized yet with vitality due to my previous Liberty benefits of which he said I mustn't worry it will be sorted out, I just need to pay the vitality joining fee & go back to gym. It is not the first time being misled by one of the staff members from this branch. And when I call him he says he will get back to me & he doesn't, so I don't know what to do anymore & I'm really dissapointed as he failed to do what he promised whilst I did my part.
