The collection company came to me. What should I do?

It is easy to solve the problem of home collection: 1. Open it and record the whole process with your mobile phone, 2. Check the number of visitors and identity documents, entrust them to get the documents (check them outside the door first) and take photos to keep them. Before entering the house, please inform that there are old people and children at home. If there are no more than three collectors, insist on entering the house, make a loud noise or threaten maliciously, and directly call 1 10.
