תרגום - יוונית-אנגלית - OK. οποτε θέλεις πάρε...

Just "call" - not "call me".

I agree with kafetzou, what s/he said is "OK. Call whenever you want". There is no "me". (though s/he probably meant "OK. Call me whenever you want" )

Sure I agree with you, though since the sentence is taken from a daily chatting I thought that it was rite .Therefore do as you think
