Does that actually work? I guess I will try - nowt to loose!!
Yes! I have first hand experience, after 3 months of trying to get Plusnet, and PN trying to get OR to fix an issue of their own making I raised the matter with the CEOs office and it was fixed within 5 days, this was an actual fault.
Numerous people have resorted to this method to get database issues resolved, and it generally works. Just remember to be clear, concise and polite.
