Just a simple sentence.

Hi all. I just wanted to learn what exactly mean " GAMW TO SPITI SOU TOURKOSPORE".

Thanks in advance.

It doesn't mean anything, it's just a collection of words. Whoever said this to you was just trying to wind you up. Next time tell them "Den asholoume me vlakies", meaning I do not spend my time dealing with stupid things. BTW indeed, why do you spend time dealing with such nasty people? (Rhetorical question).

Zvezda is absolutely right.

Such people and their twaddle are not worth wasting your time on.

) did he say something bad? Well it's meanless because there aren't any reason for said something like it (whatever means).

Well, some people can be gratuitously nasty.
Just send him about his business, dismiss him. It's not worth dealing with him.

ok whatever. Thanks a lot.
