How many days does the travel agency have to refund the outbound travel deposit after returning home? What if the travel agency delays the refund? Do you need to call the police?

It depends on the travel agency. Generally, as long as the return passport is cancelled (if necessary), the deposit of the travel agency will be automatically refunded to the consumer. Didn't you ask the travel agency the specific reason for delaying the return trip? If the travel agency you report is affiliated with the merchant, it proves that he also has difficulties. In addition, sometimes the embassy impounds deposits, which may happen. You don't need to call the police now. Sometimes the police don't file a case for you at all, and you have to pay a lot of money. Let me give you a suggestion: you can definitely handle complaints at your local tourism bureau. What the travel agency fears most is the whole industry informed criticism of the Tourism Bureau. However, this is the worst policy. If possible, it's best to settle it through negotiation. Sometimes when the complaint is over, he gives you a refund. It is really unnecessary to think about it after the problem is solved. Let's be polite to each other and solve it reasonably. I hope you can solve this problem as soon as possible.
