Is Election Commission Of India really unbiased ?

Many Public authorities in India have adopted online grievance redressal mechanism. Election Commission of India(ECI) is also amongst them. ECI is responsible for administering all the electoral processes in India. It supposed that under the supervision of the commission, free and fair elections are held. However when it comes to redressal of complaints or grievance, I doubt whether ECI is really unbiased or how? .There is reason why I doubt election commissions procedure.

On 4^th march 2014 I lodged online complaint with election commission of India. Promptly they sent me acknowledgement. Redressal time given to  my complaint was 10 days. However even after 25 days ECI has not taken any decision on my complaint. If there is no substance in complaint they should have disposed it off with reasons. What is point in keeping the complaint hanging? Why 10 days response time was given to me and what happened to it? I had lodged complaint against Pune Divisional commissioner Prabhakar Deshmukh. He has very strongpolitical backing and can easily manipulate the election procedure.
