Policy amendments taking more than a month

On the 14/08/2015 I e-mailed Sanlam documents for them to update my details and recalculate my premiums as I need to remove a dependant and add another. They acknowledged receipt of my e-mails on 17/08/2015 but guess what a month later no feedback and no amendments done. Today I e-mailed a follow up e-mail and now one of the amendments is already wrong, I'm being address as Mr. My concerns are increasing and i'm wondering what will happen in the event of my death if i'm getting such service, maybe I should get funeral insurance elsewhere. And this delay simply means I will continue to pay an incorrect premium this month.
