NON ADHERANCE TO DEED OF SALE

After numerous initial problems with the first estate agent, Marno Muller, I dealt with Moyra de Lange and purchased a property in the Northern Suburbs. I received a compliance certificate for water, yet the plumber had to come out 2 to address the problems. The outside tap is still not sorted considering i have to use a spanner to close the tap to ensure it doesn't drip. In the addendum to the deed of sale, it is noted that the situation regarding the overflow pipe and geyser will be addressed and repaired during the plumbing COC repairs - which still has not been addressed. I have made several attempts to try and contact Moyra de Lange, to no avail. I would like these concerns addressed and sorted without being shoved from pillar to post by the plumber whose company name Moyra will not give to me dispite having asked on two different occasions. Seems once the commission is through so is their dealings with you.
