mods please help move to right section

cc. lalasticlala, ishilove,

I graduated with a 2.2 in Geology from a Federal University. (First Degree)

I currently work in a bank as a contract staff. Almost 3 years now. No promotion no conversion.

I had hoped I would get converted so I can focus on pick banking/finance related course as a career. However, that seems to be a long thing at the moment.

I had also hoped to go further my education abroad, but the wait for funds keep getting longer too.

So I have decided to settle for what I can quickly grab now.

I have a flair for things related to Computer Science (Data per say) and seeing results. I am working on MySQL skill set, hoping to get some certifications in it, but I need to back it up with something since I don't have any reliable background in computer science. Companies don't just want to see your skills, they want to see some documents as proof. Hence my decision to make the University of Lagos as a place that can help me get that.
MBA is a likely choice, but I don't really know how the MBA work without some skills to show..( You can explain better to me please)

So help me decide on what I can do this 2018/2019 session as I am tired of this bank job.

Experts in the house, should I go for MBA or Post Graduate Diploma in Computer science.

Please, I am confused.

I don't know bro, the country is fvcked!
