Is my CSA stringing us along?

My first experience with a CSA is not going well. We just received an e-mail from (the CSA) stating that they are pushing back deliveries for a fourth week. At this point, we're counting on our CSA to help feed our children, and it's highly disappointing that they are not coming through.

Is this common to have so many delays, or did I get taken?
