My uncle has a bad ear. The Disabled Persons' Federation sent a hearing aid the year before last. The ear hook was accidentally broken the other day. Where can Chun 'an be repaired?

Generally, the machines donated by the Disabled Persons' Federation are taken to the fitting center, and after-sales service is not provided unless they are purchased in this center. You can find them on Baidu. Where is your fitting center? Tell the decoration master about your situation and see if you can take them to the factory for maintenance.
