As long as the stems are still green, the shrubs are still alive. It could be that they are simply slow to start new growth due to having a bit of shock, which is causing them stress. Normally, this rights itself given some time while the roots establish. All you can really do is ensure they are receiving adequate water (and good drainage) and double check their growing conditions to make sure they are receiving appropriate light.
I would give them more time to acclimate to their new surroundings.
