Hi @raybabe,
I merged your post into this germane older topic. Based on your experience Jayco does not appear to be a good ‘business citizen’ that does the right thing.
A related topic you may find insightful is
The ACCC rarely if ever takes on individual cases so it is not surprising you did not get a reply. What you need to do next is read about your rights under the Australian Consumer Law - there are many links on the Community to both Choice and ACCC advice and laws - use the Community search, or network search for them.
Write a formal ‘letter of demand’ per the ACL and deliver it to Jayco. Cite the problem, your rights under the ACL, their responsibilities under the ACL, exactly what you want and by when. It has to be written much like you are a silk in front of a magistrate, and the magistrate knows little about your rights or the case so you need to clarify it for ‘him’. If Jayco fail to respond (unfortunately that seems likely based on their history) your next step would be taking them to your xCAT tribunal.
Some companies have been seen to fob off their customers until they go formal religiously following the ACL and keeping copious records.
With Jayco’s history of ‘attentive customer satisfaction’ and ACCC action in 2017 I often wonder how they stay in business excepting for their name (same with AMP).
A last word is that when anyone buys a used product one’s rights may be but are not always congruent with the original purchaser’s rights, so be attentive to that aspect.
