Welcome to the Community @BigKev57
It is always best to research companies prior to buying from them as you have learned.
Their web site indicates they do have phone problems (if one believes everything on any web site). For completeness, did you try their chat also?
One avenue is to seek a chargeback from your bank for non-delivered merchandise if you paid by credit card. If you sent an EFT or BPay that is not an option.
You can find out about chargebacks (aka disputes) from your card issuer. The process was discussed elsewhere on the Community.
The ABN is for STEEL & WATER PTY LTD in NEWNHAM TAS 7248, that itself being a curious company name for an online merchant, although the ecommerce site could be a trading venture related to the company.
Please let us know how you go or if you need any further guidance.
