Worst Service Ever

<p>We have logged a dispute on the 23rd May 2016. to date this dispute has not been sorted. I call on a daily basis and send emails daily, not one person has been able to assist, nobody has responded to my mail, nobody will give me a managers number. I am furious, as I have not received a invoice for the month. We refuse to have our lines cut, as we are running a business here! can somebody get back to me?</p>
