I have started finding problems with my house.

I built thru BGC

1. cracked roof tiles - the roof tiler tried blaming us for breaking them.. i hate heights wouldnt catch me dead up there. The maintenance manager was alot more helpful than the roof tiler.
2. my solar hot water system is not connected so my hot water is running straight from gas - not happy jan.
3. where i had a crack in my slab it has now come thru and i can see it under my carpet. when it was laid they did an engineering test on it so i dont know whats going on.
