So around a year ago (August 2019) I got a guy to come and build a 9 meter retaining wall which is a meter high. In the retained area i decided to get paving done (by the same guy) and some other bits around the house. He ended up charging $4400 for the wall. Now the issue is that the paver's around the wall have started to sink and the biggest gap between the paver's is about a finger length.
I got another guy to come out and have a look because the original guy is not picking up my phone anymore and he stated that the retaining wall is dodgy and the post weren't put in deep enough so the wall is on a angle now (hence the gap and sinkage).
What do i do now?
Is it my fault and i bear it and get another contractor out?
Or, can i take this original guy to small claims tribunal ?
Thanks for the help :)
