If you want to do that - your call. Please be aware that you may not be anonymous by choosing that route.
Frankly, I wouldn't do that as I think it leaves you open to unreasonable attack from all and sundry. Further, the risk is that you become the focus as opposed to the questions / issues.
If you are so inclined - simply email the company secretary - at least that way you have some degree of privacy. You are the holder and you ought to be asking these same questions. After all - the dollars owed by Voclan to QBL are your dollars.
Good on you for responding without sledging - appreciated.
