I was a Joker customer for more than 20 years, since the early 2000s, but recently switched because of a series of compounding bad experiences in just the past 3 years on top of their unusually high prices.

Edit: I feel that it's pertinent to point out one of these experiences that were particularly bad. About two years ago I tried to register an IDN (internationalized domain name) with them. The registration succeeded according to their interface. Money was deducted. The domain did not appear in my inventory. My support ticket took several days to receive attention and was just closed with the almost arrogant response, "you probably did some mistake", with no further information or support. My second support ticket, too, took several days to get a response, and it was then revealed that the problem was that they weren't capable of registering IDNs under that specific TLD, for unknown reasons. That support ticket was also closed without allowing me to respond, so I had to open a third ticket just to get my money back.
