Of course it's a scam.. there is no A320 line training capacity in Greece, or anywhere else for that matter.. we have guys now on the 737 that bought A320 ratings and line training with Greek companies, Elite, Hellas Jet, never happened, money in black hole,, beware.
The world and his wife will sell you a rating and assure you that Line Training is available.. it is, but not within a reasonable time, average 6 months wait probably even with EJ.
