The clogged sink was unclogged but the drain it went to was backed up. He told me it was fixed and left but it overflows when I use the dishwasher or washing machine. He left a bunch of dirt in the sink he unclogged and he dumped the sludge water that came out into my basement toilet. When I asked him about it he said it’s fine the opening in the toilet is bigger than the sink pipe. Common sense would tell you to dump the water outside and not in a place it could cause another issue. I will not use you guys again, sorry.
