DigiCert SSL Certificate Reviews

I had to renew a wildcard SSL certificate which had previously come from Digicert. But my client no longer wanted to use the people that had handled renewals in the past (long story). I started the renewal process from the clients web server and opened up a new account with Digicert to process it. I was concerned that there might be a problem because the certificate was already registered with Digicert under a different client. But that was not as bad as me spelling the client city name wrong in the request! I found there was a live chat option and decided to use it. I was connected to someone named Sam (don't know if that is a man or woman, wish I'd asked though!) who was brilliantly helpful. They changed the misspelling I had made in my application and pretty much took me through all the steps needed and make various changes to the certificate billing details etc. so that I am the contact in the future. These people are fantastic and enormously helpful. I even got a free t-shire for being a "great customer" That's the only bit I am not sure about. I thought I was being a bit daft asking lots of stupid questions. Use them, you will not be disappoin ted.
