Negative Trader Feedback - Need info

I just joined a couple of weeks ago and I bought a programmer from a guy on here (I just needed to change the speedo and wanted to mess with the shift points) Anaways I made it a point to ask and make sure it was not vin locked making it useless to me
Long story short I got it and it is Vin locked (I'm awaiting a response from the seller that I have notified today)
My question is if he does not respond ,
Am I just S-it outa luck (buyer b ware) type thing
Or is there something I can do Thanks

Moved from US&R to NTF.

If all else fails contact bryan at pcmforless.com, he can unlock them. The last one i had done by him was $50. If you are lucky and its 94/95 programmer you are needing unlocked, andrew at www.akmcables.com can unlock those for $20...

I would just pay the money to have it unlocked.
