Tried to send in the warrant card / junk mail initiation enrollment to Marshall using the warranty card that came with the amp I bought over a month ago. Well, after 3 weeks, the card comes back in the mail as "Return to sender, not deliverable as addressed unable to forward." Next, I go online and tried to enter info there....comes back as "internal server error." What y'all think about that one? Did I miss something about Marshall USA moving or closing up shop? AND, they owe me for a "forever stamp" !!!!!
