no feedback

I have sent through an account that needs to be settled by medical aid. 100% hospitalisation covered my foot. I have sent through the account on the 2nd, 7th October. Sent email to Carecross on the 8th and 12th October. All bankmed said was they have forwarded the mail to Carecross. To date I have not received any other feedback. The account was supposed to be settled within 21 days and its way over 21days now! I am left in the dark. So this account needs to be settled before lawyers letters start coming my way...
