Why on earth would they send you just 85% of what you ordered without contacting you for approval beforehand? I'd be very leery indeed and would return it ASAP. There's no way the missing 11 inches is a miscut. You were intentionally shorted and that's just plain wrong. Did you perhaps check a box on the order form to indicate that you would accept 'all you have' in case they didn't have the full order amount?
