Quite often keys are not as unique as one assumes, sometimes they're just there to obfuscate. What's more relevant is that you have paid for a license. A whole company using the same key would not be an issue (I'd imagine), so long as each had bought a separate license.
So I'd check that the license is legit, and that I can verify it. Then I'd call the BSA, and see if I could get a piece of that R100,000 reward they're advertising
.
The high road might seem longer at first, but you'll enjoy the downhill at the end...
