SF City riders can't refund the deposit without a bank card.

I'm very sorry, if the rider in SF City doesn't have a bank card and can't refund the deposit, you can consider the following methods:

1. Contact SF City Customer Service: You can call SF City Customer Service or contact customer service through official website to explain your situation and ask for a refund of the deposit. Customer service staff will provide you with corresponding solutions.

2. Seek legal aid: If you think that it is illegal for SF not to refund the deposit, you can consult a lawyer or relevant legal institution to understand your rights and apply for rights protection.

3. Complaint and report: If you think that Shunfengcheng's behavior involves violations of laws and regulations, you can complain and report to relevant regulatory authorities, such as consumer associations, industrial and commercial bureaus and other institutions.

4. Seek the support of online public opinion: If you think that your rights and interests have been infringed, you can post your demands and relevant evidence on social media, online forums and other channels to seek public support and help.

In a word, as a laborer, you should enjoy the corresponding rights and guarantees. When encountering difficulties and problems, we should actively seek help and support to safeguard our legitimate rights and interests.
