TERMINATION OF FULLY PAID UP MEMBERSHIP

I moved from SAA Corporate to private membership on 01 March and accordingly paid for March and April membership (paid up to end April). Received no communication from Bonitas that anything was amiss - just a letter last night advising me that my membership has been terminated effective 28 February.<br> ***?? How can you terminate my membership which is fully paid up without even the courtesy of a communication??<br> Additionally this means that, for their administrative purposes, my daughter and I don't have cover until this is resolved - what if we have an accident this morning?! I am totally freaked out.<br> You people are supposed to be taking care of my health, not stressing me to death!!
