..just an update so people know we are still in same boat :
Last I heard was the June 2011 email quoting "we anticipate that you will receive your cheque by the end of July/ beginning of August."
Its now August 24th and surprise, surprise, A1 Travel fails to meet that deadline !
My holiday was paid in Jan 2010 for tavel in Aug 2010 - which means 20 months now they've had my money.
There may be a legal challenge that is possible based upon "severe maladministration" which is worthy of pursuit.
I am finding out more legal advice. More info to follow.
