I think there is Nigeria(or National) Communication Commission that regulates activities of GSM service providers in this country! If there is, it must be a useless and irresponsible Commission. The rate at which these service providers insult the intelligence of their clients is alarming. They will charge any rate at will, hang calls and messages, hold you admist of calls, etc. One of them, Mtn, is enforcing caller tune on all its customers and charging 50naira a week. Are we saying they are extorting us with approval of NCC? Is there any percentage accrued to the agency from all illegal naira collected? Is it legal for the service providers to introduce any service without the consent of their clients? There are many questions begging for answers.

Imagine, I was surprised hearing a useless caller tune on my pastor line when I called him which he did not assign for from MTN

Me too I wonder @Op
