What should I do if I can't synchronize the content because the learning machine before class is useless for two years?

If you have bought an advanced learning machine for two years, but haven't used it yet, and find that you can't download the synchronized content and the store no longer exists, then there is a certain risk. Here are some suggestions:

Understand the refund policy

Check whether there is a refund policy when purchasing for the first time and understand the refund period. If you are still in the refund period, you can try to contact the manufacturer or after-sales service provider to ask about the possibility of refund.

Looking for technical support

Try to find official website or other official channels for advanced learning machines and seek their technical support. They may be able to help you solve the problem that you can't download synchronized content, or provide an alternative.

Seeking protection of consumer rights and interests

If you buy the service or product of advanced learning machine, but you can't get normal service, or you encounter the problem of consumer rights protection, you can seek help from relevant local consumer rights protection organizations or departments to understand your rights and ways to protect them.

take action

I suggest you act as soon as possible, communicate with relevant parties and learn about the possibility of refund, technical support or rights protection. At the same time, in future purchases, we should pay attention to choosing reliable sales channels and products, and fully investigate and understand relevant information before buying to reduce the risk of being cheated.
