I've read stories of this happening with HG. I used HG for several years until just last week or so. I switched to Leaver & Co. and they migrated everything for free same day, the only difference I noticed after migration was that my website was faster.
As for the hacking, it seems as though I've read somewhere that those might not be genuine hacks, just an attempt to get more money. HG is, in my opinion (and experience with their affiliate program), a pretty shady company.
