Who called from 33170447730

Missed a call from this obviously French number without any ID. Who is it?

no, i was not at home

I got that call. Its - so far I could understand - some porcellan-factory. They wanted to envite me to an hotel, where they show their newest collection.

Don't know where they got my number!!

i was called as well
told that guy to send me the invitation, he knew my mail adress anyway...
something about porcelain from limoges?
will update if i find out more

Have been reccieving calls since April 2009 on average once every 10-14 days  but have never taken the call. Any updates on the porcelain factory? I live in Switzerland but have never been to limoges.
