What if the first-hand app can't contact customer service?

Get contact information through other channels, send an email or leave a message, and try other customer service channels. If you can't contact the customer service of the first-hand app, you can try the following methods to get in touch:

1. Get the contact information through other channels, such as searching the contact information of customer service phone, email, WeChat and social media in official website, or searching the customer service information of the company on other customer service platforms.

2. Send an email or leave a message. If you can't find the customer service phone number, you can email the customer service or leave a message in official website to explain the problem and leave your contact information. Customer service will reply as soon as possible.

3. Try other customer service channels: If the company has multiple customer service channels, you can try to contact customer service through other customer service channels, such as WeChat and social media.

Step 4 ask for help. If the above methods can't solve the problem, you can seek the help of relevant departments or institutions, such as consumer associations and industry supervision departments.
