Welcome to the communtiy @Cooper4344
It may be worth your while to read about the Australian Consumer Law and citing their advertising, the T&C on your purchase contract, and any other relevant factors, send them a formal ‘letter of complaint’.
Perseverance may pay off but depending on how and when you purchased, questions you asked, claims the salespersons made, and so on, you may have ‘bought the farm’ and the ACL might not apply. It may be categorised as a change of mind or that you were sold an inappropriate product depending on your answers.
Start by reading your sales contract for any satisfaction guarantee or return privilege and then the consumer guarantees that apply.
Although it is linked to many topics it seems yet to be added so here is Choice’s ‘intro’
When writing a letter of complaint it has to be written as if you are a silk explaining to a judge what the law is, what you are entitled to, the problem, and exactly what you want and by when. Anything else is ‘idle chit chat’ as regards potential resolution. The templates (tools) available on the various web sites are very helpful to get it right.
If you believe you have a case under the ACL or Revitalife’s T&C, email your letter of complaint to email@example.com with the subject line Attn: Mr. Clive van Deventer (he is the CEO) and if your email supports it, set ‘return recipt requested’ (not all mailers honour it). If Revitalife sends an autoreply when they receive an incoming email that is sufficient to prove they received it. You can also send a real mail letter to him c/o their Gold Coast head office or you can ask for a supervisor via their 800 number and discuss your rights under the ACL (if they appear to apply).
If Revitalife does not engage you can then use your attempts as evidence with a formal complaint to your state Fair Trading Office.
If you pursue the matter please let us know how you go.
