Query: Be very careful about ordering from The Firm

We have dealt with this company on a couple of occasions (giving them the benefit of the doubt the second time). To date we still have not received the videos that we ordered (though they assured us they would arrive by Christmas), but they have charged our credit card. Their customer service is severely inadequate and failed to provide any answers (other than giving us a tracking number for a product that has yet to be shipped). We will not work with them again and warn others that dealing with this company may cause them similar problems.
