Medshield puts adopted baby on waiting period

I emailed medshield and got documents to register adopted baby. They insist on 3 month waiting period because baby was not registered within 60 days of birth, but we only got her at almost 8 months. Tried sending emails but no proper feedback. Then now they phone me.....BUT THE AGENT CAN'T SPEAK ENGLISH AT ALL AND JUST DROPS THE PHONE!!! I AM NY NOW SO ****ED OFF IT IS NO LONGER FUNNY. I EXPECT MY CHILD TO BE COVERED NOW OR I WILL FIND A MEDICAL AID THAT IS WORH THE MONTHLY PAYMENTS AND THAT ACTUALLY CARE ABOUT THEIR CUSTOMERS!!!
