Appeal against order of mobile service appellate authority

Dear Experts, I had filed a complaint regarding service deficiency with complaint centre of my mobile service provider. After Unsatisfactory reponse of the customer care centre, I escalated the same to Nodal Officer. After receiving unsatisfactory response from them as well, I have filed and appeal with the concerned appellate authority, which is pending for adjudication. I request you to advise where to file appeal against the order of the appellate authority in case I remain unsatisfied with it. Warm Regards, Rahul Singhal
