Meanwhile on June 4, in a village called Nkong-Zok II in the Mefou and Akono Division of the Centre Region, ex-workers of the pipeline project told the press that huge sums of money were deducted as social contributions by sub-contracting companies such as ATM Services, Doba Logistics Cameroun and Willbros Spie-Capag, but never paid into the National Social Insurance Fund, CNPS. The ex-workers brandished pay slips with deducted sums with one who suffered an FCFA 117 000 deduction each month. The former workers are now mounting pressure for COTCO to pay back the sums 'stolen' from them.
