How tall is the wall? Have they started building the roof?
If the wall isn't too tall and the cells are accessible up top, convert to a high lift grouting scheme:
1) use a long piece of rebar or something similar to break the mortar fins off in the cells to be reinforced.
2) break out the faces of the of the cells to receive bars at the bottom of the wall. Probably need at least 16" to have room to tie the rebar.
3) drop full length sticks of rebar into the appropriate cells. Tie it to the dowels.
4) grout the cells. They'll probably need to use a smaller aggregate among other special considerations for high lift grouting to make sure it fills the cell. (the knocked out face shells will be your clean outs).
Go back and double check your calcs assuming a much larger than normal variation in rebar placement. It's not going to be in the center of the cell. Make sure your design can handle the likely variations.
This is assuming you only had vertical bars. If they missed horizontal bars in bond beams...well lets hope they didn't.
