Oneplan refund cant get my money back

I am very upset with Oneplan regard to getting them to paid my refund. I submitted the Pathology claim invoice on the 22 October to the claims department. It has been procesed and I receive an sms on about 25 Oct that payment with take up to 7 days. Its now 12 of November. I have spoke to different people and its the same answer yes the payment has been released from our side. I don t believe this anymore . I am waiting for how long know for refund of R390 and I need that money urgently. My policy no ********** 76
