I call bullshit. Phone metadata is saved since forever yes, but stored at ISPs, not at government organisations. There are strict regulations regarding the privacy of voice data over the phone (VoIP does not count as such though), and I don't think the secret service and military secret service (AIVD and MIVD) can do anything they like. They have more permissions, such as demanding passwords for encrypted files as long as it's not for your own conviction (while normally you have the right to remain silent), but it probably doesn't go that far. Keyword searches are probably not true.

Yes, because secret services have been known to strictly follow the law, and not do anything without telling you first.
