I am very sorry to hear of the troubles you are having and hope that I can help you, If you would like to respond to your ticket in our Customer Care department with your phone number I would be happy to call you and discuss the available options we could provide you to help with these issues your having.
The only way your hosting could "get hacked" is if you installed an insecure configuration that is using insecure permissions on files or folders. This could allow everyone write and execute access, this is not a problem with your hosting with HostForWeb, but more so a problem with the configuration or script that you yourself have installed. As far as the former problem, your mysql not working, and any future issues you might have with your hosting account you should submit a ticket to our technical department asap so that we can further assist you.
If you could PM me with your relative ticket ID now, I will make sure this is resolved for you immediately (if it has not already been resolved). We are more then happy to audit your accounts security and point out for you the possible problems, and make sure all your services such as mysql are up and running correctly.
