He left the job unfinished and with many issues; leaking toilet & radiator, incorrectly fitted bath, many gaps in grouting, fittings ruined by splattering grout everywhere, poor tiling work. Also tried to rip me off buying tools and claiming them as materials.
When confronted about the issues and told I was withholding part payment because of them, instead of discussing the issues like a professional. He immediately responded with a barrage of personal insults and aggressive threats. AVOID!
