VFS, in case all 3rd party visa processing firms, are crap in terms of updating the current status of your visa application. The only have 2 status, application send to embassy and application processed and received back from embassy. In between those 2 statuses they will not and cannot give any updates.
Firstly the embassies doesn't update them about the ongoing processes, as it involves work with no apparent gain, other than putting the visa applier at ease. I would try calling the embassy with the reference number to get an update. If you get across a good soul he(she) may update you about the status. Done so in the past and have always managed to get an update on my application.
