My attorney failed to notify me of several hearings. She proceeded without my knowledge. I lost. Can I file a claim against her?

The case was awaiting an appellate decision. the appellate court sent it back to the trial court. Several hearing were held outside of the defendants presence with the attorney of representation stating that the defendant could not be reached. Decisions were made, then sent back to the appellate court. Because of the actions of the defendants attorney, the appellate court denied the appeal by the defendant. This case then came back to the trial court where a party of interest notified the defendant of a hearing. The defendant attended the hearing only to decover that the trial courts had already made their decison on his case. The attorney representing the defendant told the defendant that she was no longer his attorney and that their was nothing she could do. During the hearing, the defendant stated to the judge that no one tried to notify him of any preceding hearings and that his address was the same as that on file. the attorney of representation told the defendant that she tried to notify him but couldn't reach him. After the hearing the attorney of representation for the defendant contacted the defendant by letter, stating that she was no longer his attorney but would be willing to hepl him if he needed it. My problem stems from the fact that while the trial court held several hearings after the appellate court had sent the issue back to it, this attorney proclaims that the defendant could not be reached; however, when the issue was considered final, she could. - Is this your question?
