Not refunded for claim 2 months after submitting

I bought a pair of prescription glasses, before doing so I submitted a quote to Isoleso(consultant Lynique de la Rey) where she verified the amount I would get from Isoleso (Bonitas medical aid sp) I then paid for the prescription glasses, received an invoice in return and then submitted it back to Isoleso(Lynique) She confirmed that all was in order and that my claim will be paid in 7-10 working days. I followed up 15 days later as I had not yet been refunded. She claimed the payment bounced due to incorrect banking details. I submitted bank issued proof of banking details (the same banking details I have been using to pay my medical aid premium for the past 3 years) She confirmed receipt of this. 2 weeks after that still no refund. Again I contacted her she said she has now (only when I followed up) submitted to accounts department and I will be paid either last Friday or today (04-03-2016) Lo and behold! I checked my account again this morning - NOTHING. I am fed up with being given the run around by this woman. I am the one doing all the following up regarding this. It is 2 months or so late, I need someone who is going to assist to resolve this. No more run around!!
