Lies, damned lies, and Databases
The problem with many current database companies is they scrape data from each other and anywhere they can.
My employer is listed on a number of business lists but another unrelated company with the same company name but without "(UK)" is also on those lists, our artwork, website, contacts etc. are show against this other firm but trying to get the details cleaned up is pointless they just say "yes we will do that" and then do nothing. We get constant sales calls (despite being listed as no cold calls) for the other company, eventually to save time I looked up the contact for this multi million pound company on the same database and called them, turns out their "listed number" is actually a seamstress in Gloucester who is also tired of getting calls.
It's bollocks but the online database company (allegedly) leave the incorrect details on their site so they can charge £10 for "further details". Then other firms are sold, or seed their data from this list.
The other thing is name, my name is the same as a chap who runs some company in London, we are constantly getting offers of data lines for central London, despite being in the south west.
Databases are valuable it seems, even if full of ordure.
