Hi has anyone use the Greek Eppy online payment system for eTepai? I am slightly confused which reference number I put in my bank transfer. There appears to be two numbers. One is exactly 20 characters long but is referenced administrative fee code. The other reference appears to be the payment reference, but it begins with two letters followed by 23 characters the cruising association suggest it should be 20 numeric digits, which initially led me to think it was the administrative fee code  but after reading it again it would appear that it is the payment reference I need to put in. I’m just not sure where to start whether to include the two letters or just do the first 20 numeric characters. Has anybody actually use the system recently?
