Extremely bad and slow service!. I moved in saphyr court in brand new property and within six months there was a leak from toilet and mould started appearing. I don't know what they did to cover up, but the mould has appeared at the same place.
Now they are cutting corners and dibt want to know. It was reported when the property was still under defect period and same place and same problem has started again.
I will have to take a further action now.
They do not even deserve 1 star!.
