Kamatera vs. SeFlow 2021

(very mobile) user, with quite flexibile needs: Office VBA programming (8 GB RAM, quad-core), medium graphic design (16 GB RAM, six to eight cores).
I choose hourly billing cycle.
Account management is very simple and clear and support is awesome: fast and focused on solving problems / questions

here is more technical complicated issue at hand (more than stop/start server), a solution can take look, or is ignored. Here are my annoyances, to warn other people. I have communicated these to SeFlow as feedback and asked my remaining credit back. They refused in which I gave them a last chance to do this, or I would post this feedback online. So here it is. :)
- Several times I have encountered that the CloudFlow virtual server was turned off unexpectedly. When I reported this, the answer was more or less: "this service is not great, you should take the more expensive one".
- Several times I have encountered that the CloudFlow virtual server did not start after a shutdown. I had to open a ticket to request help for repair and start the server.
- I have had issues with the billing of this virtual server, where the changes of resources (CPU, RAM) did not reflect the hourly rate. Although this got fixed, it took a lot of time and wasted effort from my side.
- I recently (March 2021) encountered a failure that the virtual server did not run. It was related to the fire at OVH. But there was no communication until I opened a support ticket. After that the communication appeared, which was very lean and more or less blaming OVH. There was no decent recovery plan or any real announcement/advice what to do next. The server is still offline and cannot be started. I cannot even destroy it.
- The support team puts the blame several times at the software or services of their partners. It is the other one; not them.... Strange, I thought I had a contract with SeFlow and not with their partners. ;-)
- The company does not do refund: "There is no refund policy". Charming, while so many problems.
If you chose to use SeFlow, which I advice against, add the minimum of credit, since you won't get anything back. Even if their services are under performing.
