Yup, our tiling job was absolutely shocking by 101, got it resolved numerous times and they still didn't get it right. In the end, the job was taking far too long, and we ended up accepting below par/barely acceptable level of tiling. I think I could tile better than their guy did. It was really bad initially, and when they repaired it, it improved but was still pretty bad.
Was happy with the workmanship of all their other workers, just the tiler (paver wasn't the best either, but not in the same league as the tiler)
And yes, we had massive delays and the house that we were told would be ready in November, ended up taking till April for handover.
