No Internet Coverage AGAIN!!!

I've Just About Had Enough Of Submitting Tickets For One Issue, I Have A Problem With My Internet Connection Once Again And I Have Restarted My Router A Couple Of Times, There Is Absolutely No Coverage At All And Last Time When I Submitted A Ticket, I Was Not Assisted, I Tried Calling And No One Answers. I Really Did Not Want To Write This But This Is Absolutely Not Right, I've Paid For This Service And It's Not Working Once Again. This Has Been Going On For A Very Long Time Now And I'm Really Considering Canceling This Because I Took The Best Package Yet It's Not Working. This Is Very Frustrating.
