Article (56) Where the consumer of an electronic service places his/her order through electronic communications, a service provider shall comply with the following: 1- make available to the consumer of the service appropriate, effective and accessible means which allow the consumer of the service to determine and correct input errors before placing of the order. 2- acknowledge receipt of the order to the consumer of the service without undue delay and using appropriate electronic communications. The order or the acknowledgement of receipt shall be deemed to be received when the parties to whom they are addressed are capable of accessing it and the acknowledgement of receipt may take the form of the provision of an already paid service where that service is an electronic commerce service. Parties who are not consumers may agree otherwise. Article (57) Unless the parties agree otherwise, the consumer shall have, where contracts have been concluded by electronic communications, the right to rescind or terminate the contract within three (3) days from the date of entering into the contract as long as the service provider does not fully implement the contract in a manner that serves the purpose of the contract during that time and the consumer does not use the goods or products which he/she receives nor receive any benefit or value from them. Article (58) Unless the service provider and the consumer agree on another period for delivery or contract performance, the consumer may terminate the contract with a service provider where delivery or other performance of the contract is delayed for a period exceeding thirty (30) days and shall be entitled to a refund to any payments made by him/her under the contract for the products, services or other contract performance affected by this delay. A consumer shall have no obligation to pay for any goods, products or services that were not ordered by him/her nor pay for the cost of returning such goods including any goods or products delivered to the consumer by the service provider by mistake. A service provider shall have an obligation to notify the consumer of any delay or other difficulties experienced by it that have substantial effect on the contract performance. 23
