Medical Aid Terminated

I am truly disgusted with this medical aid,4 days before i need to go for an c-section they terminated our medical aid due to us not telling them i was pregnant...we were already members with them when we found out,how are we supposed to tell then if we didnt know...they could have done it more than a month ago so we could have made plans but 4 days before ?? Worst medical aid. They wont have me as a member ever again
