Head straight back to the shop that did the work and give them the chance to recheck their work. Some transmission flush machines are designed to pump in exactly the same amount of fluid they pumped out. It's common for some to spill out when connecting the hoses, so the procedure is starting with low fluid level. That will result in low fluid level at the end of the procedure. The mechanic should have checked the fluid level before returning the car to you, but that can't be done on some newer models. Often mechanics are pressed for time too, and they just assume the level is correct without checking it.
You didn't list the mileage so I don't have any idea how much wear has taken place inside the transmission or if it is likely there was a problem you were trying to solve with the flush. Too many people think a flush will correct some symptoms that are caused by mechanical problems including wear of the clutch plates. Also, a lot of mechanics are convinced flushing the transmission on high-mileage cars leads to new transmission problems. The fiber material flakes off the plates but stays suspended in the fluid where it adds to the needed friction on those plates. Flushing the fluid removes that grit, (which should be a good thing), but some mechanics think that's what leads to problems after a flush.
If it is determined that the clutch plates are worn excessively, and the transmission needs to be rebuilt, it is important to understand that the flush didn't CAUSE that problem. It just made the inevitable problem show up a little sooner. When there is no excessive wear yet inside the transmission, flushing it won't cause any damage.
