Well thats a new one AIFOS taking someone else to court !!!
Makes a change from the hundreds of people pursuing them for Money !! They owe me over 76K Euros.
Won my court case when they offered no defence, Still wating for our money. Its likely we will never get it
as they will almost certainly be in administration/bankrupt very soon.
My advice would be to throw the demand in the bin.
However its likely at some point in the future the Administrators may try to pursue this if you are seen as a legal debtor.
Clearly you need legal advice as to whether you actually owe it them.
