Poor service and uninformed client

I was with BCIMA(Universal) for bit more than two years never have I received a statement that showed outstanding or rejected claims every statement shows a closing balance of R0.00 which I have proof of and since I am not with them anymore I received a tax certificate with a R3170 claims not paid by fund, if there was any claims not paid why hasn't it been put on the statement also they cannot tell me which companies claims has not been paid also who will ever know when they have outstanding dept. if you receive a closing balance of R0.00 every month I feel like I'm being ******. Nobody has ever contacted me stating that I owe them money or that my Medical aid has not paid. I also only had one authorised claim done with them and called almost ten times to confirm if the expanses would be fully covered. I have not received any proper feedback nor assistance form them nor a decent email trying to explain this.
