DigiCert SSL Certificate Reviews

We had previously used SSL certs from another well known provider. Last time we renewed I toyed with the idea of switching to digicert, but I got cold feet due to the possibility of something going wrong on the server when switching providers - since I was not in the same country as the server at the time. This week I was reminded that our old cert was expiring and assumed there would not be enough time to to the validations etc, and I am also due to leave the country tomorrow - so I went back to the old provider (whose staff had kindly informed me yesterday that the cert was expiring tomorrow), and their staff promised to call me back "tomorrow between 3-4PM". By 8pm no one called, so in exasperation I tried their online chat - it was not functioning - so I called them - and was told the person handling the case was not in today, but "someone will call you back within 1 hour". But they did not. So, I went to Digicerts site, opened a chat window and some pre-sales chat (not pushy) ensued, then I decided to go for it, and the whole thing, from the start of the pre-sales chat to verifying our company documents, issuing the cert, installing the seal and having some chit-chat while we waited for various emails to come arrive, was over in about an hour and a half - the rep I was dealing with - Taylor - was very friendly, courteous and helpful and gave me quick responses to all my queries. Also please note: I am not a system admin guy - I have a little knowledge about these things, which can be a dangerous thing. But in any event, there were no problems and the cert is now up and running. I would not hesitate to recommend digicert based on my experience.
