Not a good one

We have ordered medium vermiculite many times but we just discovered today that you sent us the coarse grade. This is disappointing because we could get coarse grade in town. We pay the 14.00 plus in freight to get medium and have never had a problem until now. We did not notice when the box came but using today for planting did not get the results we do from medium.
