Confidentiality in regards to dealings with Strata Managers

Hi

Can I please ask if anyone is aware of the requirement of confidentiality in regards to dealings with Strata Managers. I recently called and spoke to my strata manager to complain about them, only to come home to find that they had emailed the whole executive committee saying that I had complained!  There has also been a follow up email to everyone asking for me to retract my complaint as it unsubstantiated.  Surely this is unethical?

If anyone can assist it would be appreciated… I have lodged a formal complaint with the Dept of Fair Trading also…
