Network Solutions SSL Certificate Reviews

After ordering it and getting stuck in a "submit csr then wait for email" loop for weeks and thinking it was an email filter issue filtering their email. I finally called them 5 weeks later and they said they had sold me a 4 year cert and they no longer offer it and that is why it wouldn't go through. So, they converted it to a 3 year and then when I submitted the csr I had the certificate within 15 minutes or so (the only decent part of the whole transaction). They package my purchased certificate with 3 others. One appears to be the trust root certificate and two intermediates. Should be straightforward to install it. NOT! 10 hours later and half the business mad at us because email keeps going up then down, I finally call them for now the 5th time I think. They said the separate certs would not work and told me to combine the public portion. So, I did that and it still won't work and the email is still hosed. Ultimately, I went back to our free self-signed certifcate because we were having a LOT less email being rejected than we did with their cert. I usually use GoDaddy and since they had an existing account with Network Solutions I thought it would be quicker. I am going to contact their accounts area tomorrow and try to get a refund. If we don't get one, I will dispute the charges. In my 18+ years in the industry, this is the absolute worse SSL experience I have ever had. Avoid these guys like the plague.
