Thankyou Jimmy T and Whale,
Your advice is much appreciated. I thought the issue was resolved so I sent the strata manager a quick email just to get some feedback and I recieved further complaints. I know that we have done everything possible and I am not one to cause problems so your advice @Whale about 'ignoring' them is the best tactic I can employ.
If down the track this issue continues I am now armed with your advice to move forwards whether it be through fair trading an AVO or a lawyers letter.
Thankyou so much!
