Worst Web Hosting Providers - Real Life Experience

I work in the field of web hosting and those are the worst web hosting providers based on my real life experience. They made me lose money, clients and they affected my business reputation in a very negative way.
1- ServerHub: they suddenly suspended my account and so all sites under my account were suspended as well and after contacting them they said that it's because of error happened with their billing software that caused my account to be auto suspended. I had some clients moved their host away immediately.
2- HostNine: I had VPS with Host9 and i had outage for more than 7 days.
3- Tuned Hosting: Had a reseller plan with them for good price they promised that i would be able to resell shared hosting plans with up to 8GB of RAM and 8 CPU cores. But suddenly the service gone down because one of their nodes was restarted and all data was corrupted (that's what they said) and it took them around 8 days to restore the service and after that they dropped CloudLinux and used CentOS instead and now i lost the ability to be able to resell shared hosting plans with up to 8GB of RAM. i asked for a refund since July 2017 and i have not been refunded yet.
4- PacificHost: They suddenly changed their plans from unlimited reseller to limited. And when i asked why they said the management has been changed.
Those four really hurted my business so bad avoid them at any cost.
