Awaiting response on Urgent Emails sent

I made a phone call to Fedhealth Customer Service to inform them that my pay date has changed to the 15th of every month so they need to change it as there will be no payment for them on the 1st of every months every more and they must do it quick before the suspend my policy ( same **** I had last year, they never listened and suspended and terminated due to not reading emails), I was informed to send a email to the member department and so I did and asked for them to please confirm that they have changed it, it is now a week later and the 1st of the new month and I still havent received nothing. I have sent 2 emails stating URGENT PLEASE RESPOND, all I receive is a ref numb and that is that no confirmation that my PAY DATE HAS CHANGED.Now I am worried that due to bad client service they will suspend the policy, just cause they did not read or do as email requested. FEDHEALTH is becoming a big problem CLIENT SERVICE WSE. I am still struggling with other older problems as well.. so they dont deliver as they say on their TV ADD. Very Worrying...
