One Silly Action And I Land In This NIMC Bitter Mess Now

Please, great Nairalanders, I implore you to advise this young guy on his identity predicament.I'm a guy in my early twenties. I was tempted to use a false name during my NIMC registration and for that am now in deep water. I changed my surname from an Igbo name to a Yoruba name. I also changed my farthers name to a Yoruba name just to fake my identity as a Yoruba guy. Why?Few years before I started my work as a machine operator in a nail making company, I had been working with a private security company as a security guard. I was working with two other colleagues at an MTN office. One of them was an Hausa guy the other was a Yoruba guy. The Hausa guy was working on a 24 hours basis and I normally joined him only for night shift but the Yoruba guy normally worked in the morning as my reliever. Along the line, I noticed some irregularities in our work: the Yoruba guy, after his morning duty, would come back late in the night with touts and harlots and would spend the night in the MTN office and that's how they had been doing before I started work there. Seing the mess, I warned the guy that I wouldn't tolerate his actions and to stall his actions, I began to lie just at the entrance of the main building every night. Out of frustration, however, the guy came after I left and broke the glass door of the main building to implicate me. He reported me thereafter and I was called to explain what happened to the broken glass door. When I got there and saw what happened, I use the opportunity to explain all that had been happening in the night. So the panel that called me appreciated my action and fired my two colleagues: the Yoruba guy and the aboki. But thereafter, the director called me aside, gave me money in appreciation but also warned me not to continue my work there because the Yoruba guy that normally brought touts with him to mess up the venue every night and all his friends are cultists. It was as a result of this and other threats that I left the security company entirely. When I started work with another security company I changed my name to a Yoruba name for protection without telling the company my real identity as an Igbo guy. The new company then posted me to a nail making company a little farther from my previous location. Two months later, after working as a security man in the nail company, I made arrangements with the Accountant of the firm and he decided to help me to join the factory workers as a casual staff. First he asked me to go to my security company and tender my resignation. while I was away to do this, the Accountant just picked my wrong name and sent it to the company's headquarters. When I came back I didn't bother to tell anyone am an igbo guy. I was also made a member of the company's staff cooperative society. The second year I was asked to bring my guarantor because they want to make me full staff. It was then that I decided to tell them that am an Igbo guy. They were very sad because they took me for a Yoruba guy because I was so fluent and eloquent in the language. As I was trying to let them know the security situation that led to my action, they didn't want to believe me. In the meantime, I foolishly went ahead to NIMC office and registered the wrong name there so that I would quickly open an account with it and get my money out of the cooperative society.But the accountant said I shouldn't use the wrong NIMC slip . So, I went to register for PVC, I then opened an account with a bank. To correct the error in my name, I got a court affidavit and a newspaper publication for that.Now, the crux of the matter is this: I need to change the wrong name that I registered at NIMC. I have been struggling with this for a long time but their supervisor that they refaired me to said I should go to Abuja to sort it out. Please what do I do?
