Consider sending a copy to the boss's boss too, and to any groups that have helped you, or might be able to help you. Another idea is to arrange to meet with your social worker or their boss. Before the meeting, practise what you're going to say. It often helps to take someone with you to a meeting. If you haven't been able to resolve your problem by speaking with a staff member or their boss, you may be able to make a formal complaint.
Many government agencies have formal ways to complain.
Most formal complaint processes involve letters or telephone calls, meetings, interviews with staff, and a review of any files that have been kept on your case. If you decide to make a formal complaint, ask the staff for information on their formal complaint process. In B.C., the Ministry of Children and Family Development can send you a brochure about its complaint process. Instead of phoning, it's generally better to write a letter saying that you are making a formal complaint. Keep in touch with the people who run the complaint process and keep notes of who you have contacted and what they said they would do.
