Our townhouse complex's mailbox have been tampered with more than a week ago and we have not received any mails. Does the local Post Office keep our addresses' mails in the office (like mails being put on hold when people go on vacation)?

Yes! If the Mail Carrier notices any suspected tampering with mail boxes, all mail will be held in the office. Just go to the counter and provide your I.D. to the Clerk and explain what's going on. Now, has any one notified the Management Company or Owner?

Yes they would keep the mail at the post office until it is fixed so you can go talk to your local post office and see what are they doing about it .
