I have 4 years of using it and works perfect, support works, uptime works, they give me whm, etc...

I have had an email problem on Site5 for nearly a year. It no longer provides telephone support and writing a "ticket" about an issue is summarily ignored. A few days later, after submitting a ticket, an email from site5 is ... Daugiau received after each ticket that says. "since we have not heard from you the issue will be closed". I have sent several tickets complaining of he same issue numerous times and each time the issue is ignored and followed by the same email to me. There isn't even a statement that the issue was read.
I have therefore moved my website and hosting to another hosting company but Site5 relentlessly bombards me with email about the issue it refuses to resolve. I lost a lot of business because emails I sent to customers from it's server were consistently bounced from gmail, aol and yahoo email accounts because the Site5 server was insecure by gmail, aol and yahoo.
At this time, nearly a year after submitting the first ticket, and several months after moving my website to another host, Site5 refuses so acknowledge that I am no longer a customer. They keep sending those useless emails about the ticket being closed. I need to make sure that any future charges to my credit card that are attempted by Site5 are blocked since customer service has not deleted my account, even though I specifically sent a request to customer service insisting that my account be closed (and even though I have removed my website and email to another host).
Site5's support is Horrible ...the worst...it is non-existent!! I suspect there are no live support technicians working for this company, hence the spitting out the same canned email month after month to me "closing" my ticket without ever addressing my problem , and giving no pretext that there was even an effort to address the problem.
Go somewhere else when looking for a webhost. Mažiau
