Pogos Plumbing No Longer In Business

On 7/21, we had furnace cleaning, and then after they are gone there was no hot water comes out. I noticed it on Friday night, and they did not fix it until Sunday. The hot water tank's fire went out because they cleaned the furnace.It was working perfectly until Friday morning. My complain is they did not check the hot water tank's fire after they cleaned chimney because the fire go out automatically if the new air comes in. They should have known this as professional. If they call the technician right after they cleaned the furnace I did not have to wait for 2 days without hot water shower, and I did not have to pay the weekend labour fee which is much higher than weekdays labour fee. I talked with the manager about it, he said " It(the fire) was working when they leave. The fire went out after they left." I had doubt what he said. Then I talked to with the water heating company technician asked about it "Is it possible the fire goes out slowly after the cleaning?" He told me "If the fire go out, it blow out right away and not like after they left" Therefore, what the manager told me is not correct. I would suspect that " Their cleaners did not check if the fire went out." that is also their(alberta home service) technician was told me exactly.
