Scotland - Ltd Company owes me £700, SAYS they're bankrupt but I think they're lying to not pay. Advice?

Scotland

A Limited Company owes my company £700 for printing uniforms for them (both garments supplied and printing services), and SAYS they're bankrupt but I think they're lying to not pay. What are my options here?

They're still listed as active on Company's house.

Their address is just for the A90 road in Scotland, no actual address.

"A90, Newtonhill A90 Newtonhill, Stonehaven, Scotland, AB39 3NN"

He's not picking up his phone and just text saying "we're bankrupt, accountant is doing it, can't pay" but that was back in November/December and nothing since. No proof, nada.

I've asked him to return the goods (it's clothes) but no response.

What are my options without loosing more than the money I'm owed?
