Shower and tiles by local pros

I’d like to give feedback on a job done by someone from local pros- tiling a shower and fitting the shower doors. Someone from local pros that admitted he doesn’t tile anymore were sent to do the job - he mentioned this when he started struggling and wasn’t upfront from the start. It took 5 days. It is not neat at all. Now the drain is clogged with cement. If he can’t do the job why was he sent for this? I spend money to get something done according to standard. I trusted the website that said you do tiling and renovations. Now I sit with a shower that I’m not happy with. The plumbers that came to fix the drain couldn’t believe the mess that was made
