Glo Nigeria Cut Down Their Data Volume

The Grandmaster of data (Glo) seems to have been unable to keep up with their promise on data bundle. Despite its epileptic network, people are still managing the Glo data due to their cheapest plan. The complaint of their customers didn't give them the courage to fix their slow network issue, but they went ahead to frustrate users the more.
Last week, Etisalat reduced their weekly data bundle from 200MB to 150MB for N200 and now Glo NG has chosen to follow suite.
Old Glo data Plans
N500 = 1.6GB 7days
N1000 = 3.2GB 30days
N2000 = 7.5GB 30 days
N2500 = 10GB 30days
N3000 = 12GB 30days
New Glo Data Plans
N500 = 800MB
N1000 = 1.6GB
N2000 = 3.7GB
N2500 = 5GB
N3000 = 6GB
 
If you look at the old and new plans, you will notice that they just slashed everything by half. Is this not going to chase away their subscribers?
