The Nigerian Communications Commission has said it has developed guidelines to curb the menace of unsolicited messages, mails and calls.
If you suspect any fictitious thing, hold off and call your service provider. Otherwise call NCC on 0800 2255 622 if the network operators were not able to resolve the issues. There is no charge for calling this number.
Notice that it could be a problem to give millions of subscribers one line to call, but at least there is a process. The government must develop a system that will enable its services to have an impact. One telephone line will not help, in this case.
