A german friend of mine, who speaks neither dutch nor english has found a pinball machine (sorry, video game

) he wants to get on markplaats.
As it also already happened to me in the past, he is not getting any answer to his "foreign" email, and there is no phone number. He lives just on the other side of the boarder and would like to, simply put: "go buy the machine and go home with it", for the sellers price.
As the dutch community is very well represented here in this forum, would it be possible to get a hand here? The phone number? Or to write exactly that to the seller?
The buyers name is Marcel, and his email is marcelpeetz@gmx.de if the seller wants to get back to him.
Or through me and through this forum would also be fine. Greatly appreciated.
Many thanks.
