Dear farahnas,
If contacting Emirates Airlines has failed, my recommendation would be to file a formal complaint with the Department of Economic Development, Government of Dubai. They take consumer complaints seriously and as it is a government body and Emirates is a Govt of Dubai airline, you are most likely to have a resolution. I understand that this seems like an extraordinary step so the decision lies with you whether to file a formal complaint. Below please find the links you require.
Department of Economic Development, Government of Dubai:

Government of Dubai Unified Customer Complaints Portal (eComplain):

For your reference, please find a link to a list of Dubai Consumer Rights which is issued by the Dept of Economic Development:

I wish you best of luck and a speedy resolution to this issue.
