Medical Aid bill not paid

09/02/2015 I did a general check up using my Medical Aid (GEMS - Emerald), my bill of R1500 was settle by the medical aid to Lencet with an outstanding balance of R95 which I paid thereafter. On 17/08/2015 I received an SMS from Lencet saying I am in errears of R1464.68. I called my medical aid and I was told they had a system error and reversed all payments (including mine), when trying to pay again my account was exhausted After going pillar to post fighting with GEMS, 08/10/15 Bongani Khambule from GEMS confirmed my account with Lencet will be settled in full. 10/10/15 I received an SMS from GEMS saying Lencet wil be paid 16/10/2015. To my surprise, 20/01/2016 I receive an SMS from Lencet to say I'm still in arrears and my account has been handed over to Debt Collectors. 20/01/2016 I called GEMS to query this and I was told it will be investigated but since then no one has came back to me. I've been calling almost everyday, spoke to numerous team leaders (Yandiswa Myeko, Debbie Nieuwouudt, Mpho Mbeshu and Michelle Andrews), they all promised to call me back but non of them did. I am tired of calling everyday and not be given a feedback, can you please assist me in this regard.
