Web host not responding and I refered a client

Repeated bad service means the host isn't going to change himself soon or ever. Move over to a better service provider. Usually you get refund but I doubt you'll get it after 8 months. If you're serious about your clients, and you seem to, then get the absolutely pro hosting to save your own reputation from going down. Do a proper research before you move on to another host and get a SLA and uptime guarantee if you're going for anything above shared web hosting.
