Problems vir Internet ASDL

<p>Our internet connection is so slow and sometimes non existing, Have logged a call on 28/02/2017. Nobody even bothered to contact me. The call centre can;t assist so what am I to do. </p> <p>My account is always paid up to date even though the servise received is very bad.</p> <p>I am running a business and the Internet is something I can not do without.</p> <p>A while ago we had a problem with out telephone line and a technician came out, I still have a problem as the technician said he thinks it is the instrument, I have since replaced it but the problem still persists.</p>
