Amazing support but unfortunately a ton of problems thus far.

I wrote a review regarding HostAfrica support praising them for the excellent support they provide but I have never had so many issues with a hosting company. My sites just went down for over 40 minutes because they decided to do a server update and restart mid-day on Tuesday. My websites were down yesterday for over 20 minutes and they can't see why. I transferred a new domain over to HostAfrica and after the transfer was completed I was advised that DNSSEC was enabled on the domain by the previous domain admin. I contacted support and asked if this would be an issue and if they supported DNSSEC and if they don't support DNSSEC and this will be an issue what should we do to rectify this? I was then advised by Zolani that this won't be an issue. I repeatedly asked Zolani to confirm this which Zolani did. After days of struggling to get the SSL certificate to generate throughout my website, I was advised by another consultant that DNSSEC is not supported and is currently the cause of our SSL struggles. (I should mention that we did get the certificate to work later that day). At this point in time, I no longer feel comfortable moving my customer's websites over to HostAfrica and will be monitoring the performance of HostAfrica for the time being.
