For me, it is most everyone / every institution I deal with. Maybe not all excellent but almost all are and always have been good to very good or better.
Last night my water meter froze (in the cellar!). Got up today, no water. Called the water Co. and they said they would send someone out with a new meter. I asked about how long, the gentleman said w/in an hour he hoped. (!!!!) I was amazed and told him I had actually expected to hear something like 3 days. The guys (2), meter and truck were here in 2 hours, changed out the meter, made sure nothing leaked and did a quick volume test, all w/in 45 minutes, including going to the street to turn the water off and back on again. IMO, excellent customer service, just like most of the customer service I use / run into.
Had an LED light strip power supply quit last week, ordered a new one from Ebay, got it w/in a couple- three days, and it worked..... for 0.2 seconds. I wrote to the co. that sold it and they said sorry, refunded my money (including shipping), told me to keep the one I had and asked if I wanted to buy another. Again, fine customer service (a garbage product but that would be a very different thread).
