Some unscrupulous people in Dormaa-Ahenkro in Brong Ahafo have been using used phone cards and metals like needles and blades to manipulate the pay-phone system in the town.

Mr Isaac Gyan, District Manager of Ghana Telecom (GT), who disclosed this in an interview with Ghana News Agency at Dormaa-Ahenkro, said the practice was seriously affecting the quality of the company's services.

The District Manager warned such saboteurs to desist from the practice adding that the Company would deal drastically with any one caught.
