Line is not working correctly

<p>Hi</p> <p> </p> <p>Our line is not working correctly for a long time now, since December. Noise on line and ADSL is not working too. Your technicians come on site say they fixed problem but as they leave it doesnt work again. Can technicians please call me when on site. As they seem to arrive and leave if no one is home. If they give me a heads up I can open up for them if needed inside the house.</p>
