Can't make usage metrics work

[Kamran]

Greetings,

               I'm developing a module for my service which tracks usage information and my current module works fine, usage metrics which released for WHMCS v7.9 attracted me and hence found a use case for my service but the issue that I am facing is usage data won't update (not even once!) I've followed all these links including Usage billing feature doc, Usage metrics provisioning module doc and class doc whereas have posted my relevant code and details on whmcs community under whmcs 7.9 beta discussion but did not recieve any help so far on this issue below is the link for that post:

 If anyone in the community(either from WHMCS staff or anyone ) knows what's wrong and can help it'll be much appreciated as this feature is quite important for my organization.

Thank you!
