As many above have said this really is their problem to fix.
In your shoes, I’d write to the most senior person at Intense and the distributor. (I mean the CEO, MD or some such; don’t bother with a customer services rep)
Simply set out the issue you have (no bike) and what you want them to do (provide you the means to have a new bike, of an equivalent type and quality, for no additional cost).
Place the problem firmly in their court
