They're a decent service but they were acquired by GoDaddy (who I think are douchebags) so I stopped using the service. But I have been forgetting to actually cancel it for years now.
For a while they were changing me ~$10/month. Nice for them and not painful enough for my lazy ass to jump though whatever hoops they may have set in place to cancel.
Then one day I let the balance on the debit card they have on file for me fall to zero, so their auto-debits were failing. Eventually they sent me an email saying that they would stop charging it, but... They will (and do!) try again from time to time. Just to see if it will work.
Rather than just cancelling the service (that I haven't touched in at least 4-5 years) they leave my account in a zombie state and periodically attempt to harvest it again.
(EXPLETIVE DELETED) cheeky bastards, eh?
