What can be done if court changed name on birth certificate?

When Donna was born, (my friend I am helping as a Health Advocate) an error was made by the hospital and not caught by her parents or her. Her mother's name apparently was put as her name on her birth certificate. She went all her school age as Aldona, and when she was working went with a lawyer to court to have her first name changed to Donna. She did not have ever have an original birth certificate, but her lawyer said he would obtain one. After the court proceeding were over she had the court document signed by the judge and filed in the circuit court with the proper seal. She has used Donna as her name ever since. How she is of age to start paper work for Social Security who wanted a copy of her Birth Certificate. She is having difficulty because they will not give her, her birth certificate because she has no proof she belongs to it. They said she has to go to the court again and have them open the court case and refile it to change it from her mother's name to Aldona to Donna before she can have it. She does not feel she needs to do this because she paid for it and it should have been done correctly the first time she was in court. How can this be handled now to help her since she is now not in the best of health?
