Six months of no ADSL

We have been reporting the problem since the beginning of the year. We reported the fault again on 22/06 ***. We then tried again on 11/07 Escalation ***. It is now the 22/07, a full month later, and still nothing. We are trying to run a business yet have no Internet/ E-mail yet come the end of the month we are expected to pay for a non existent service. Our business is suffering as a result. This problem has been going on for over a year now. GET THIS FIXED!!!
