Frontier Slow or no service all the time deland Nationwide

 I have made numerous calls to the tech support. I have been told any where from there is line faults, to much traffic. half the time i have so slow speeds. and no internet at all. to red internet botton on router. everytime i have a tech here they tell me there is no problems. my speed is good. yet 2 minutes after there gone the red lite comes on. the router has been replaced and yet nothing changes. They have given me so many stories my head is spinning. They keep telling me they are sorry and updates to the boxes are in store but never an idea. i keep getting some credit but i hate paying for something i dont get. i dont really have any other place to get service cause im in a small town. do not get this service it isnt worth the frustation.
