Only Coinfan will be able to comment on the specifics regarding the legal action they were (or were going to) undertake. I hoped this matter would have been resolved by now because the OP did not deserve to be mistreated in such a manner by Rock Trading.
I hope the Rock Trading apologise and settle this matter returning the funds owed to the OP.
But how it's possible Coinfan that in 4 years the authorities to do nothing about your case?
Why not opening a civil law attack against their company? I know in Italy things are slow in justice, but not 4 years slow..
