If you have a complaint, you need to resolve this matter directly with the operator. Alternatively, the Department of Economic Development website provides details about complaining effectively.
Talk to the accommodation provider first (generally they will have their contact details listed on this website or with booking.com). If the provider does not resolve the issue to your satisfaction, you can further your complaint by contacting the Department of Economic Development or Ajman Tourism Development Department.
Your financial institution (credit card company, bank etc.) may be able to help dispute charges on your behalf.
