We repair computers, but we don't have a store. I want you to help us think of an idea, see how to reassure customers, and let us take the computer back for repair.

Unless you know where your home is, or the computer is about to be scrapped, the computer will be worthless, or customers in Shen Hao will let you take it back for repair.

In fact, there is a way to send a text message or do a WeChat home repair, which will generally let you go home for repair. You said that others would not refuse to take it back for repair, and I did the same.
