I was an online.net costumer for a lot of years for a personal project, and a happy one, but then they changed the contract unilaterally, which included the billing going up almost 75% with another changes in the ToS. And look I get it, sometimes prices rises, and you can always change providers, so the problem was not that... but the customer service and poor communication.
I only notice the change, after my credit card notified my of a higher charge than the ones I'm used to. There was not notification about it in the dashboard. And after a lot of tickets with representatives, they told me under the excuse of "ram / hdd prices are going up" the notice was send through email, and probably gmail mark it as spam... and then the nightmare to cancel begin.
After telling them to cancel the account, they told that under the new contract (that I didn't accept) they could only do it if I got charged another extra month, even if from the start you always payed one month in advance, plus paying the setup fee at the beginning.
Look I get it, hardware it's messy and prices can go up to stay in business, but this attitude of "I am altering the deal, pray I don’t alter it any further" was the one that made me look for another solutions, and be skeptical about Scaleway despite in paper being a good alternative to Digital Ocean (that let me tell you, DO customer service it's gold in comparison to what I got from online).
