Eeeek i feel your pain honey the bridal shop i bought my dress from went into liquidation and she left the lady who bought her stock and customers from her to sort it out, i ended up having to pay another £348 to get my dress as she hadnt paid the full ammount to the suppliers i didnt and still dont have wedding insurance and paid using debit card, but was able to claim money back under the visa chargeback scheme if you pay using another debit card you would claim using their corresponding scheme if they have one, in the end i got £208 back from visa, i could have registered a claim with the administrators too but after H2B's dad ( an accountant) looked through the paperwork for it he said she was oevr £100,000 in debt and only had £6000 assets so it would be highly unlikely i would get anything back from them.
Maybe you could try contacting consumer direct, they were an absolute godsend for me, their number is 01209 720333
