I cannot see Greek Banks handing out Credit Cards willy nilly to all asundry just to clear their tax bill.
Proof of income, E1, ability to pay, regular deposits, credit history, etc...
My Local. Gvt. pension is sent to HSBC (their bank) this is then forwarded to the bank of my choice, UK at the moment.
If I could by-pass my UK bank and send it direct to Crete (I say Crete because HSBC have branches on mainland Greece but not Crete) life would be easier.
OK they do use Bank of Cyprus...but... mmm
Unable to get any contacts from my pension Dept. re HSBC but still trying.
I realise you have worked in Greece Warwick so maybe it was easier for you, as with a certain document I have to wait 5 years for.
