Hello,
1. This was not an EMERGENCY call.
2. You clearly state; "Plumber friendly and helpfull, quickly identified the issue, gets part from the truck" (so the Plumber was excellent and really a PLUMBER ON DEMAND)
3. You were charged 215$+ HST for a cartridge replacement (which you dont mention, and it's by far very reasonable)
4. A refund was applied 3 hours ago to your credit card, without you even asking (just because you are a seniour and we don't wont you to get a heart attack)
5. Buzz off, and never call us again.
