Refund? Class action?
Refund: Definitely an option...if there is money to refund.
Civil action: (not class) PITA and only the fucking lawyers win. Plus it is very hard to enforce any judgment.
There's a very good reason Consig always suggests using USPS money orders and shipping via USPS instead of PP, checks or Fed Ex or UPS. They’re called Postal Inspectors and they live for mail and wire fraud...and they’re free. Just sayin'.
