Berlin or not Berlin?

Hello I'm living in Spain, I'm French, I'm working since many years (I'm 27) within the customer care service and also as an helpdesk level 1.

Now with the crisis I want to leave Spain and I'm really attracted by Berlin, for its culture, nightlife, etc... But I don't speak German, so I wonder if there is some call centers where is they just need native speakers? Is it easy to find ? I'm suppose to move within one month! My second choice will be Manchester.

Thank you!
