A boy hacked your mobile phone. Later, you changed your number and texted him, but he didn't answer the phone. He changed his number twice and still didn't answer, and then it was all the same.

Needless to say, boys are not interested in you at all, or even disgusted with you, so they will take such an absolute approach. Because they don't want to have anything to do with you anymore, they won't answer text messages and phone calls until they don't answer all strange calls. They are afraid that you will call him at another number. Obviously, you have no room, he can't contact you, and he never wants to have anything to do with you. In this way, you should give up, no.
