1. If you don't think they gave you the product/service that they promised, and you paid by credit card, contact your credit card company (preferably BEFORE paying the bill that this charge appears on) and explain the situation to them. In the past I've had great success in having my CC company go to war on my behalf.
2. Call Widow's customer service center. Having to wait extra time for them to fix the thing is annoying, but if it's their mistake in the first place then they should really be paying for shipping. Maybe you can convince a customer service rep to have the thing shipped at their expense.
In either case, keep records of everything. Keep your receipt. Keep copies of all correspondence with them. If you call them on the phone, take notes while talking, including the time/date of the call and the name of the person you talked to. This kind of stuff will make things much easier on you if it comes down to an actual fight.
Two things to try
