Cancelled policy without consent

I have been with discovery for 7 years under my employer. Once I changed ownership to be debited directly for my account, they instead cancelled my policy WITHOUT sending cancellation confirmation. Without notifying me of such. I called in to ask why my premiums isn't going off when I'm actual fact it was cancelled. Please bare in mind, I have a three year old child with cardiovascular problems as well as a brain defect. Please ****ing tell me DISCOVERY what would you have done in that situation?? Let alone call them today and complete utter **** service , I was told someone will call me back. I'm sitting with zero medical aid with a child that is DEPENDANT on it! Useless company!!!
