Fault service request closed without resolution

A month ago I had slow connectivity and intermittent connectivity. I opened a fault log and was contacted within a reasonable amount of time by a technician saying he was working on my fault which was also a similar fault to what others have reported. Thereafter I heard nothing. I followed up a while later to find that my service request had been closed. I tested my line and the line speed was fine so I thought it was resolved. The very next day the same fault was still there and so I opened another service request LINKed to the previous one. I have since then found that my neighbors are experiencing the same issue of slow line speed and intermittent connectivity. I have been contacted and told that once again a technician will look into my fault. But seeing that this has been an issue for me and my neighbors for about a month WE are concerned that this will once again NOT be resolved and our service requests closed.
