Two top business subscribers to Nigeria's largest telecom operator MTN are questioning their recent bills from the country. Messrs Uman Okon Umana and Senatro Anietie Okon have said MTN is billing them without cause and forcing them to pay higher fees. Umana, the Secretary to the Akwa Ibom state government, is angry that MTN in December 2010, sent a bill of about N3.07 million for him to pay for the month, saying the details of the bill did not sit well with him. Senator Okon has a similar case, where he is repudiating a bill of N527,790.19 he was alleged to have incurred in September 2010 . Making both cases known to ICT reporters in Lagos, Communications consultant of the duo, Iboro Otongaran who is the CEO of Ikeja based outfit, Pro Data limited, said that an international business outfit like the operator could put its customers through such harrowing conditions. MTN through it General Manager, Corporate Communications, Funmi Omogbenigun, told reporters that the company promised that the issues would be promptly addressed. She quickly dismissed claims that MTN does not care for its customers adding that it is in the company's interest to ensure that its customers enjoy the kind of quality of service, information and complaints resolution that they richly deserve. According to Otongaran, “Our client Umana has been suspended from the MTN network after he rejected a bill of N3, 073, 612.36, which was nearly 3000 percent above his monthly credit limit of N250, 000. He rejected the bill because it was in excess of his credit limit, fictitious and arbitrary. BM
