sharp practice and corruption would continue because there is no enforcement and the punishment is not steep enough to prevent or deter the corrupt practice. any marketer caught trying to cheat or is corrupt, should be immediately fined a massive amount and their license banned for a period of a year. Depending on the offense, there should be some jail time involved also.
Asking marketers to pay 250k is small compared to the benefit they get from corruption and sharp practices. only strict enforcement and massive penalty would begin to reduce corruption in Nigeria.
