The law is definitely taking over as MTN has be slapped with a back to back fine, and every single fine has resulted in a huge amount payable to two West African countries- Nigeria and Cameroon. The Cameroonian government has fined MTN $160 million yesterday. The fine, which was incurred for failure to pay taxes on games and gambling services, was equally extended to other telecommunications firms, including Orange and other companies. This came off the heels of an investigation into the sector, leading to a total fine of $283 million that included Camtel and Viettel which were also in violation of the regulations.
In the report written by CONAC, the Cameroonian anti corruption commission, MTN and Orange were also accused of not paying taxes on their money transfer system, known as Mobile Money.
The Nigerian Communication Commission (NCC) had in October 2015, issued a landmark fine of ₦1.04 trillion against MTN Nigeria, but MTN in counter moves initiated legal proceedings against the NCC.
With the fines hitting from back to back, these are definitely not good times for the South African company. One thing is for sure though, MTN is not willing to say “Egbon government, if you want the money you can come and collect it”
