Ok, so it is not often i get asked to write a review after a difficult order. But full credit to Craig from GNP. He took my calls, actively worked to resolve the issues with a 3rd party. He called me with updates. Im tired of no issues reviews asked.
I’d buy again from GNP, because they (GNP) had my back. Thanks.
