Virgin active and debit orders

So about 5 months ago I closed my Absa bank account and moved to nedbank I then got a message from Virgin active to say my account is in arrears I went there paid it and then gave them my new account number since then I also changed phone numbers and hadn't been attending gym and then I got a email to say there is R1000 In arrears so I went to Virgin active george area I was in at the time they swipe my card say there is nothing in arrears went to Virgin active in Constancia asked them the same thing when I went to play squash there then I get a call on my Landline to say that I've been handed over for not paying so I go to Virgin active in Claremont to sort this out at first they don't want to help me then a gentleman comes and says if I take out a new contract they can only help me so I did that he then said to become part of Discovery again I must pay R1800, so I take the option where you pay R150 joining fee and the R200 higher premiums a month because I can not understand why I have to pay for discovery again, anyhow I pay the amount that Virgin gave me for the account being in arrears, and after all of that I'm still getting messages from Mbd to say I'm going to get blacklisted etc I've been a member with Virgin for over 10 years and this is complete nonsense never have I met such incompetence and lack of organization and no one is willing to help you unless they get there commission once you've signed up they don't care
