Better to put a new application if you applied more than 2 years for sponsorship. Waiting for a hearing date is waste...
OR
Write a letter to appeal office stating that you been waiting long enough. It's good to keep bugging them to remind them about your hearing. Write the real reason to have appeal fast. Send all your recent proves pictures, email, everything you have.
You have to give 3 copies. 1 to your lawyer, the Ministry, and to your case officer. Call the appeal office and ask for your case officer name. All proves and letter copies should be kept with you. Make each copy and send to LAWYER, MINISTRY, and to CASE OFFICER. When writing the letter, state in salutation who the letter is for (Ministry or the Case officer). My lawyer never told me about this, I found out and was offered for an interview on March 2015.
Good LUCK!
P.S. You have to make the appeal office open your file, and bug them few times.
