There is a flaw right from the beginning of your post, you wrote

"As at 7th of December 2015, Naira to dollar stood at ₦250 to $1, which was the highest fall of Naira to Dollar in history (Reference 1). As at today 28th of December, 2015, Naira to dollar stands at ₦197 to $1 (Reference 2), this shows there is an improvement"

Below are my opinions.

#1. It shows you didn't do a good research and like so many "copy and paste blogger" just paste some reports for us.
#2 You didn't thoroughly read through your reference.

Your flaw is that you gave a Black Market or parallel market rate for #250 on 7 Dec and you quote Central Bank rate as of 28th December which stood at 197.

When I saw your quote above, I had to check because never in the history of Nigeria have we made any significance improvement at any time.

There are several problems to our financial crisis.

1. Misappropriation of fund.
2. Avoidance of taxes e.g black markets is a big market yet no taxes would be paid to federal government.
3. Corruption.
4. Zero Accountability. e.t.c

Solutions:

Every kobo of federal gov. must be accounted for.
Taxes invasion is a serious crime and highly organised one,government must be willing to penalize even those in government
Reduce Nigeria's current corruption level by 10% for a start.
Funds must be spent on projects not pockets.

Same experience same route another airline, the thing is you call their office you get one info and you get to airport another.

Brazil Embassy would give you letter or if you go to embassy before traveling at all that you don't need one that you should go talk to airline.

I have switched back to recording conversation on my phone, so I have valid proof.

For the judges learn or I wish you good look in your experience.

For those who have experienced this, I feel your pain,please move on.

Nigerians are bad, Nigerians are bad,tell me any country where there are no bad people.

I have lived with foreigners who do bad shits that I can't even do yet they open mouth and condemn Naija. But When you meet a well travelled and experience foreigner, no matter age,race or status they tell you humans are same everywhere.
