Medical suspended due to THEIR slack service

Hi! I have just recently upgraded my medical aid plan with Bonitas. I had to phone them to find out whether the option had been changed. I had received no communication from them regarding this. But received a text msg informing me that I owe them R321 and some cents. I paid it immediately as I depend on my medical aid (we have a child). While talking to agent I asked why I never received anything from them re opt change. After I pd the above amount I received txt informing me that plan had been changed. Rcvd e-mal last night about another outstanding amount. called, this amount is short pd from option change that had been changed on 1 jan15 (only received txt informing of option change on 14 jan15. I do not have R1600 to pay the outstanding amount right now. They WILL suspend my medical aid shuld I not pay it before end of FEB? I ask you Bonitas. who's at fault here? Check your communication with your clients. We pay to have medical aid, and receive this treatment.. Not ON. Thanks Nara and Ndumiso for trying to help me. But it's still not sorted! Please get back to me ASAP.
