No technicians available

About a month back my 10mb line went from being usable to completely pathetically slow. We normally get about 6mb bit at the moment we only get 0.04mb. I reported the error and it has taken nearly a month... Not to be resolved but to be assigned to a technician. I am still waiting for it to be taken by a technician to be resolved. It is not linked to a general network fault and all I need is someone to come around and test my line. <br> The call centre is unable to tell me anything about why it hadn't been givwb to anyone. Calling them seems to be an exercise in futility as they have no power to force the issue. It has been escalated so many times but still no resolution. <br> All I am asking for is to be able to use the services I am paying for. If i stopped paying then you would send someone out immediately. However as I am a good customer your company feels completely satisfied with giving shameful service! <br> Wish there was another option!
