Your frustrations are quite warranted, however in fairness to the Company, they did send a second revised date, accompanying the prospectus, on a seperate paper.
This date was to be April 15, last Friday, however circumstances outside the company's control, or at least not initially forseen by SRZ, have inhibited this date, and as the stock is not listed, the only vehicle for S/H notification is via mail.
As no definitive date has been agreed upon with the ASX at this point, a date cannot be made available on the ASX site.

Currently, they are endeavouring to notify all S/H's of a concrete date as soon as it comes to hand.

Personally, l think that during this maelstrom of selling, the delay may prove quite favourable.

However,for your own piece of mind, call the company.
