Cabelas lied about my $400 backorder to try to screw me $960 for the same order! Internet

Cabellas took my order for $400 worth of ammo that was on backorder at the time with expected delivery 2-3 weeks later.  After waiting nearly 1 month I called to inquire on the status; at which time I was told the expected wait was extended another 3 weeks.

I then recieve an email 2 days later indicating "Unfortunately, we are unable to get authorization on the credit card that was used on your order.  Please contact our Customer Relations Department...".  I immediately called my credit card company to check for a fraud issue.  My credit card company indicated there was no fraudelent activity on my account.  They further indicated that I had ample credit line availabilty and that there had been no declined responses.

I then called Cabelas with this information.  They indicated that they tried to charge my card and could not.  I then confirmed the card information and informed them I had already been in contact with c.c. company and there were no issues and no attempts by Cabelas.  I asked to use another card and was told my order was in a hold status and would have to be completed the next day when c.c. processing was open.  I asked again to use another card and was told my order could not be completed.  I asked for a manager.

The manager simply reiterated everything already said and indicated she could not help. I pressed for my order to be completed at which time she admitted they were sold out again.  She said they would not be getting anymore in like I had ordered it, ie. a promo package currently selling at nearly $1000 that I locked in at $400. I indicated that I believed that fraud was being perpetrated against me and I wanted my order completed immediately.  She gave me the to corporate and ended the call.

As a side note, I can buy the exact ammo I had a confirmation for, but at the nearly $1000 instead of my order of $400.
