Sad News: Etisalat Increases Prices Of Monthly Data Plans

I don't really know what is wrong with this Etisalat NG. At this particular time, when competitions growing stronger, other providers like Glo is tirelessly increasing their data quantity at lowest prices. Etisalat doesn't learn anything from her opponents, just busy doing unrelated.

With deep regret in our heart to alert you that Etisalat NG has just increased the prices of their new monthly data plans;

Before now, Etisalat;
1.5GB cost N1000,
3.5GB cost N2,000,
5GB cost N6,500,
8GB cost N8000 and
10GB cost N10,000

The newly increased prices of Etisalat monthly data plans;
1GB, is now N1000
1.5GB, is now N1200
1GB + 500MB night plan, is now N1000
2.5GB, is now N2000
3.5GB, is now N2500
2GB + 1.5GB night, is now N2000
Is it a system error? Could it be as a result of launching her 4G LTE service in the country or due to the current economic meltdown and recession?

What do you have to say about this Etisalat unsatisfactory data plans?
