And I strongly hope that you can take it to be fixed as soon as possible to ensure it can not hamper my work and life.
In this sentence , it refers to my telephone. It does not work. I think the clause ' to be fixed' is grammtically wrong. Could you give me some advice? 'can not' is not proper. How about ' will not'? Thank you.
The sentence is fine as it is. You could use "will not," but this does imply a willfulness that telephone systems usually lack.
