WHMCS integration does not work?

I have posted few of the questions seeking solution for my website in respect of whmcs integration. However, I am sorry that I could not get satisfactory solution. I request the support team to kindly take this issue at their level by using the login credentials of our wordpress so that whatever needful is required may be done at your end. I have been waiting for more than 13-14 days and bound to request you to intervene in my wordpress application.
