Shri Kanhaiya: Your role as a whistle blower in refusing bribe has landed you in an unenviable position. With no help coming from any quarter, probably you can try to ventilate your grievance through the media and it may help. Paint the picture that you have been wronged in refusing to play the bribe game. Your efficiency would lie in 'playing the victim' role to perfection.
Shri Sharma: You cannot make out a grievance for the fact that the complaint was taken back, still the organisation can investigate the matter. Wait for the investigation to be over, cooperate with the investigations, put up your defence strongly and try to persuade the investigators to see your part of the story.

Dear Umesh,
Resignation always needs to be accepted by the management. If your management says that investigation is pending into the complaint lodged by the customer, you ask the management to complete it as early as possible and relieve you accepting your resignation.
