First of all, the strata is Perth Property Care and you want to stay as far away from these people as possible. You will be spoken to extremely rudely and feel miserable after you interact with them. When trying to speak on the phone he said "oh there's a call coming in bye" and hung up the phone..
I have had the same response from the builder regarding the water pipes - both cold and hot being loose, rattling, water hammer (two loud booms in a row) and these two loud blasts that can be heard coming from the entranceway in the building. All these noises can sometimes be heard various times every hour through the day. When the plumber was here he heard the loud blasts and he said it was not the pipes? and walked off. Wtf?
HY Pipes is responsible for this and they are not taking responsibility for this. Highly unrecommended
