Poor service

My advice to anyone considering using this plumbing service is to avoid it at all cost. I called them to clear a blockage in the kitchen drain of my condo because the sink was backing up black sludge. The roto-rooter plumber arrived and tried to get a snake into the p-trap below the sink, but too much water leaked out when he tried this. After a three hour service call ($330), he fiddled around and didn't accomplish anything. He then said he's have to come back the next day and have the building manager tell the other units to stop using their water before proceeding. After wasting so much money already, I decided to go with a different plumbing company the next day. The new plumber arrived, put a snake through the sink hole, and after a 30 min service call, the blockage was cleared. At this point, the p-trap could be opened without any leakage. I spoke with the Roto-rooter manager (Brian) to complain, and request some kind of refund for the poor service. He was rude, unprofessional and in the end, actually hung up on me. So, I did not get any form of refund at all. I would recommend going elsewhere for plumbing services.
