Painful claims process

Best believe they will make it as painful as possible to claim back your money. I submitted this claim in early May and was asked to provide documents not readily availble by the medical aid. Their attitude is that you have 180 days to claim but they dont care about the client or their circumstances who is waiting to be reimbursed. I submitted all documentation on the 14/06 and I was notified of payment failing due to my account being closed and I did not update this which I understood is my fault. However since I provided the correct banking details, this is the third payment that they continue to process to the incorrect account.
