In the Bible we see the Apostle Paul appointing Elders in the various Churches he established. In terms of the Deacons, Acts 6 indicates that the Deacons were chosen by the people - "choose seven men from among you who are known to be full of the Spirit and wisdom." Acts 6:3 In terms of the Elders of the Church, the choosing process is controlled by the qualifications laid out in several passages: 1 Peter 5:1-4; 1 Tim. 3:1-13; Titus 1:5-9 (and many other passages.) We do not see in Scripture where there is a process of the congregation "voting" on individuals based on popularity or business acumen (and a host of other non-Biblical criteria) as we see in current culture.
So, how are Elders chosen? I suggest that the Spirit of God Himself raises up men in the congregation who are Spirit led people who want to honor God with their lives, and gravitate to the qualities that are clearly spelled out in Scripture. And thus, the congregation recognizes whom God has called into leadership. Is it "wrong" to vote on who will be an Elder? Answer: no. We see from Scripture that the congregation recognizes the ones within the "body" who are qualified according to Scripture, and a vote for Elder is a confirmation that the individual who is placed before the congregation is truly qualified by the Biblical standard.
We rejoice when God is moving within the fellowship of believers in raising up leadership in the body. And this particular congregation of believers is blessed with leaders who qualify for the offices according to God's Holy Word.
