RDS Plumbing & Sewer

RDS owes me money for double charging me and will not pay me back.

RDS Plumbing double charged me and will not pay me back

Because I was stuck in a lurch late on a Friday after being flaked on by another plumber, I was braced to pay for afterhours / overtime fees  But even though I was calling around 5p, RDS still said they would charge me their normal flat rate for drain clearing.  I later confirmed with the guys that did the job that that was "just how we do it".
I had to wait a couple of hours while they finished up their scheduled appointments for the day (no big deal, there), and they gave me a heads-up phone call when they were a half-hour away.
Two guys rolled up in a nice van outfitted with all their tools, etc.  They were super nice and polite and got straight to work.
They fought with the drain from the sink end for about a half hour to no avail (it's some janky pseudo-industrial plumbing with unusually tight bends that didn't want to cooperate with the unclogger) and ended up having to disconnect the vent stack and drop the router in from above.  Got the drain cleared easily from there and the water flowed again!
They provided a written 6 month warranty on the drain staying clear, as well!
