I often keep a handful of partially-filled combs (both honey and pollen) in the freezer over winter, which I de-frost to room temperature for 24hrs before donating them in the spring - never had a problem doing this.
Sounds as if you've produced something the market doesn't want - or isn't ready for just yet. Comb honey is a bit of a niche market, as people have become conditioned to buying jars of thick amber liquid. Sections and cut-comb used to be all the rage at one time.
Suggest you 'get out there' with a few samples of your existing stock, and talk to 'whole-food' shops, health-food shops, delicatessens - indeed, anywhere other than bog-standard food shops or supermarkets. If you find some takers - you're sorted. If not, accept the reality of the situation and do as tcj1 suggests - reduce those combs to honey and jar it for sale 'as and when'.
One idea I've seen is to place some comb honey into a jar, then top it up with extracted honey as a 'novelty presentation'. Doing this does create something of a 'farm-produced' product - as opposed to factory mass-produced - but whether this would sell in your location, couldn't say. So much depends on local customers - around here people are strapped for cash, so supermarket Chinese honey wins every time.
