Disappointed in Discovery Health!

I'm so disappointed with discovery health. I was with them for 17years and had to change to my husband's medical insurance when I left the company. My husband passed away on the 5 th may and I was looking at going back to discovery... They say my application is approved but won't have cover (emergency or otherwise) for 3 months as I was not with a medical aid... I have. 5 her old child... How can I have no cover for 3 months??? And with only 1 income now, I simply can not afford for pay for the insurance as well as the discovery premium... SO DISAPPOINTED!!!!
