At present your are or should be on a list as a creditor. Kroll who are the administrators of the business, are in contact with a number of potential buyers at this minute, so the store may or may not be saved.This doesn't necessarily mean that any new potential buyer's will honour all Allders debts. Paying by switch card as left you in a void at the present time. Had you paid by credit card,then you would have had some protection via Section 75 of the Consumer Credit Act 1974, and the credit card company would have had 'equal liability'to help resolve the issue.
I would suggest,that you either phone or visit the store and ask for Kroll's contact details. You should then be able to have a direct information line available to you.Some items like carpets were sold by arrangement with other companies, beds may have a similar arrangement, so best to contact Kroll and find out, do not really on shop assistants, as they can only relay messages, and in some cases they are in the dark as much as you are.
