Taking my ring in for repairs they got liquodated i have no ring anymore.

We took my ring in for tje stone to be reset back in my diamond tanzinite ring. We never got a call back for the quote amount or sms. Got to Cape Gate doors were locked like realy locked. 2 Weeks later my husband got a call from Tygervalley branch if we still need it fixed he said offcourse so we tolk them the brackenfell branch is close. So they told him they are just locating everthing to tygervalley branch and will fixed it. Another 2 weeks past we decided to go to Tygervalley branch got there they were also locked down, went to ask American Swiss if they know what was going on they told u. NWJ is in liquodation. We tried calling Durban branch until today no luck they took my ring and i have just to accept this. We we went to ask them to fixed my ring they should gave know the are going to be liquidated as you have to apply 3 months before they should have told us. I am asking here were can i file for requesting my ring back or my money for the ring bought by them for R6500 less 50%. Or can i go to the papers?
