Consider the following:
The public authority of consumer protection (PACP) is anauthority working for consumer rights in sultanate of OMAN. ThePACP aims at protecting the rights of the consumer and ensures thatprompt solutions are provided on consumer complaints.

After signing up the consumer’s login into the PACPe-portal and enter the details of the complaint. The systemcategorizes the complaint and forwards it to the concerneddepartment within PACP. There are two main departments handlingcomplaints. The product complaint department (PCD) handlescomplaints regarding products and the services complaint department(SCD) handles complaints regarding services. There are multiplemangers working in the two departments of PACP who are assigned thecomplaints by the system according to the nature of the complaint.When a manager receives the complaint, he starts working on thecomplaint by collecting information about the complaint. Theinformation regarding the complaint is collected from the consumerand the product / service provider. After the necessary informationis collected regarding the complaint a case is prepared with thedetailed observations of the manager handling the complaint.Observation written by the manger normally identifies the nature ofthe complaint and necessary actions to be taken on the complaint.The case with the observation of the manager is forwarded to thehead of the department for approval.

The PACP Staff prepares detailed reports on thecomplaints which are shared with the public via the e-portal
