In Nigeria, many organizations believe so much in paper qualifications. Whereas there a lots of people without the requisite paper qualifications but will do very well practically on the job if given an opportunity.
What I'll advice is that you step up your status as per qualification. That is, try to upgrade by getting your MBA/M.Sc. This will brigthen up your chances. Also try to enrol for professional qualifications.
Not withstanding, keep trying any job openings; there are lots of organizations that don't discriminate. You might just be lucky.
Above all, commit it to God - He's the one that qualifies the unqualified!
