We switched to using StartSSL some years ago for our SSL certificates. Their pricing model is attractive, pay $60 for personal identity validation and issue as many certificates in whatever configuration you like. Pay another $140 for EV validation. It all went great in the beginning. However, in recent interactions they’ve become increasingly antagonistic.
At first they refused to issue a replacement for an expired certificate, saying that we needed organisation validation (an extra $60) first. We were able to issue the same certificate 2 years ago without this extra $60. Then they became downright obnoxious by email, deciding they were now unhappy to discuss our account with me.
