holiday vouchers.. supporting company gone out of business.. help

m13drk

Last year I was given £600 of holiday vouchers, part of the small print was there had to be a minimum of 2 travellers and the holiday had to be booked through top class travel in Manchester. At the time I had no one and no time to go on holiday with.. I rung the agent at the time as there was no use by or expiration on the vouchers and was told they would be honoured indefinitely. Especially to the timescale I was expecting to use them by end of 2013. I now find myself with someone and the time to use these vouchers only to find that jet2 have taken the agent to court and had them wound up and have subsequently ceased trading. Is there anything I can do? The vouchers were provided by a different company working in partnership with top class travel.. do ihave anything to lean on them with? I know this seems trivial, but as a self employed guy ive not had any time off in 7 years.. this was my chance to afford to take the time off thanks to the substantial reduction... Many thanks..
