Non plated through hole to PTH
If you have defined the holes correctly, then the fab should do a repeat run for free to correct their mistake, and they should do it expedited if you shout loud enough. However, this is not going to get you boards tomorrow.

Do you have a 2-layer, or more-layer board? 

If you have a 2-layer board, then you can do a repair, as you have access to both top and bottom copper. Clean them of any solder resist round the hole, and pass a pin or wire through the hole, and solder top and bottom.

If you have a 4 or more layer board, and you need connections to the inner layers, then you are in much more trouble. There is no easy way to do this. 

You might be very lucky and find that the inner layer connections come out somewhere else close by on the board, and you can link them there.

If not, there are products on the market called things like 'PTH repair kit', that claim to be able to plate the inside of holes. These are very difficult to use and get good results, especially if the board has been through a complete fab cycle. You will need to drill out the hole a little larger, to get access to clean copper on the inner layers.

How much larger depends what sort of mistake the fab made. If they built a non-pth hole, then inner copper will stop with a clearance back from the hole, and you need to expand the hole considerably to pick up the copper. If they built a pth hole, but didn't plate it for some reason, then the inner copper will meet the sides of the hole, and you only need to clean it by drilling slightly larger.
