Your lawyer has to give you advice but £7000 to go to court looks expensive and you should question this
the storey is that Huma have now stopped making voluntary refunds because they expect a decision very soon.....now being commercial
They must have offered you alternatives:- MCC swop at 10 % below their current price and ready now or Tabernas at a discount
Quite a few have taken the MCC option because they want Spain now
If not then perhaps your lawyer is not up front with you!
Face to face seems to have produced some good results for many...may be worth a trip over to see Huma....take your recorder!!!
Some lawyers want class actions to make money but not all....I am told
