Are you saying that the three rejected shops all had specific guidelines that stated that, if the package was rejected initially, you were to ship it ground?
If this is the case, you should be able to quote the guidelines to the editor and, if needed, project manager.
If not, the error is yours and the shop was rightfully rejected.
Either way, the BBB is not going to help you much as it it a consumer advocacy group and your relationship to Ipsos is not as a consumer.
Hard work builds character and homework is good for your soul.
