The bucket with all their unnecessary rebuild junk left next to the toilet. For those who have frustrations dealing with AI and auto-booking... they have an annoying robot who books appointments who cannot differentiate members from non-members. Took two phone calls and 6 minutes to connect to an actual human.The things meant to help are harming us. Pay people, not machines. Regarding machines, the plumber took a quick look and confirmed it was the fill value not doing the job. Something I told my mom I could fix easily with a part from ACE. He quoted $368 for a rebuild, which didn't need to be done. I replaced the flapper and chain about a 6 months prior. Not only is this an easy DYI fix with a $20 part, but he tossed the 6 month old flapper and chain. He tossed the work I just did. THIS DID NOT NEED TO BE DONE and it's insane to charge that much. It already costs members $69 to come out, and $368 is with the member discount. I am not the home owner, so I have no say so in approving the work. I have builder friends and my neighbor (HOA) agreed the price is insane. $437 to fix a $20 problem. This is 2026 and my mom is on a very limited fixed income. I spoke to Ben the manager, asked for a breakdown. If the up-charge was the parts or labor. He said there is no break down and that's what it costs. I could not have been more angry with these people. If you know nothing about plumbing, than learn. Because it ridiculous to be charged that much for something so easy to fix.
