Answer 1

What is the actual problem? Does your service returns the exptected result? If so, you should save it to a variable and then you can bind it in the html. component.ts

data: any;

getCountConact(){
  this.dashboardservice.getContactCount().subscribe((data)=>{
    this.data = data;
    console.log(data);
  },(error)=>{
    console.log(error);
  })
}

and html:

<div>
{{ result }}
</div>
