Paving Masters Shoddy Workmanship

I hired Paving Masters (Patric Sabau) from an ad on Gumtree, to pave my driveway. I accepted his quote and he did the job on 19 August 2020. It is the worst workmanship i've seen. The paving is very uneven, forms a huge hollow against the building, which causes water to dam against house wall. The lines are very uneven and the quality of the pavers are poor as they break and peel. The gaps are not grouted and some gaps are very wide. No base or sub-base was used and area not compacted after laying of pavers. I contacted them after the job and although they promised to return, they never pitched. I am now forced to hire another vontractor to fix there shoddy job. People I contacted are Patric Sabau - *** and Trevor Majino - ***
