This case concerned a dispute between a telecommunications company and a customer on the payment of invoices issued for services rendered. The claimant, a telecommunications provider, argued it was entitled to payment for services based on issued invoices. The claimant relied on the invoices as evidence of the contractual relationship and the amounts due, asserting that the invoices were subject to the regulatory oversight of the Communications and Information Technology Authority, which supervised billing and service delivery within the telecommunications sector. The claimant maintained that the invoices constituted a formal document establishing the right to payment and reflected the customer's use of services. The claimant argued that the failure of the customer to object to the invoices or cancel the service implied acceptance of liability for payment.
