8 weeks and still not resolved

we reported our phone line and ADSL line out of order in January. It is now the first week of March and a technician came out ONLY last week to fix the phone line and told us to buy noise filters for the ADSL - it is STILL NOT WORKING WITH THE FILTER - we have phoned over 1000 times and no one comes back to attend to the problem. I URGENTLY need this for work purposes. The amount of calls to get someone to come out over 6 weeks later is appalling. this needs to be attended to URGENTLY!!<br> Reference 1: 674crk270116<br> Reference 2: 820654<br> Reference 3: 1055CRK020316
