Can some body please tell me the authorization code of 3ds max4?

I've tried contacting autodesk a lot of times for providing me with the authoriztion code of 3ds max,but for each time they said they'll be sending that within two hrs of my request but they never did.I've tried finding it through many other sources,but none of the codes worked as each of them are already in use.Please suggest a relevant code.I really need it!
