Uber complaint system is useless

My daughter never used Uber before. Suddenly on 7 Sept 2019 3 charges to her account and total of R1478.73 empties her account. I cannot contact the call center as they need my account, which we don't have. On trying online. They need the account details and contact details of account holder. That we don't have as do not have an account but have charges. So the system is useless. No one to contact unless I have an account I don't have an account but got charged trough a bank account.....
