According to its Charter the CSC will not become involved in a direct dispute between PTI and any registry operator.
PTI has a well-functioning complaint process (see: https://www.iana.org/help/escalation-procedure). If you have a complaint, please submit it directly to PTI, by filling out the form on the Customer Service Complaint Resolution Process webpage: https://www.iana.org/form/complaint.
If you are not satisfied with the resolution of your complaint, PTI will provide you with information on how to further escalate your complaint to PTI’s management. The CSC is informed of any such escalations and – in accordance with its Charter - will review these, with a view to identifying any patterns of poor performance by PTI.
