My colleague s mobile phone, which I had just bought for three months, was placed on the kitchen tab

What kind of colleague is this, don't bother with him, it's too unreasonable, if you really bring him a loss, you can repair it, if he is really more serious, then there is no way, that is, there is no money to compensate him for what he can do with you, you don't have to care about the hurt feelings between you, he has already denied your feelings, just finish with his hippie smile.

Do you have a good relationship with him? If the relationship is not good, then there are many ways to solve it, such as calling the police, or using force to solve it, and if the relationship is good, then you can discuss it with him.

There is such an unkind person, break off the relationship directly, and get along with him is ashamed. As for whether a phone is worth it? He must have bought it and regretted it, and he wanted to change it to find fault, so he could consider solving it by force.

Dip the rag in some dishwashing and wash it.

Find two people to get him, I'm afraid you'll be fine.
