Bear in mind who they are
"With its brands 123-reg, Heart Internet, Host Europe, Webfusion, Host Europe Suisse, Domainmonster, RedCoruna and Donhost, the Group has a strong market presence in the UK, Germany, Austria, Switzerland and Spain."
If 123-reg are negligent like this for years without telling anyone, it's pretty certain that the other companies are just as bad.
I had no end of rows with 123-reg over a customer's FTP hosting where they just deleted files from an FTP account that only I had access to. Literally, the whole site, just disappeared - all sorts of CGI and back end code gone and all the HTML removed (obviously I had backups, but that's not the point). When I reported it (because it broke the website I'd just made for the client), they then phoned up my client(!) and vehemently shouted me down to my client to the point where relations were very strained all round. I demanded a conversation with their top technical guy and recorded it. I still have the MP3 somewhere, because they were basically phoning up my customers (i.e. the details on the webpage, not the owner/technical contact on the domain) and telling them it was my fault and I'd deleted all their website.
The technical guy said they'd had no data loss. But they didn't have backups of ANYTHING I'd uploaded over the last six months. Nothing at all. I demanded they change the FTP password on the account because if *I* didn't do it, and I was the only one with the login details, then *SOMEONE* did and I needed to secure the website. 3 years later, the password was still unchanged despite a LOT of requests on my part. They had no FTP access logs AT ALL, to prove me wrong or see if they'd had an intrusion. Nothing. Not even a list of IP's from their authentication system. They could not even tell me when I'd logged in, and I'd given them my IP. The technical guy at least had the decency to start sounding sheepish at the point they realised that they had no way to tell what had happened, and that I probably had more logs than they did.
The client eventually moved over to a completely different host, and didn't blame me - mainly because they were annoyed at being rung up by someone not associated with them at all who them proceeded to blame the guy they were paying for something they hadn't even noticed up until then - but it's those sorts of things that cost you customers (and initiate lawsuits!).
It's a shame. For a while, I had hosting and accounts with several of their now-subsidiaries but they've all gone to pot in the intervening years.
