If you actually tried all the options possible (which are limited to emailing or calling, in this case?), I would try contacting the embassy of the visa you are applying for, since VFS is are supposed to be working through them anyway. It usually takes VFS little time to transfer the documents from the embassy to the VFS office, so knowing if the embassy's work is done and the visa is issued, you will know that the passport is coming, or you will at least be certain to blame the delay on VFS.
