5 weeks, 10 faults logged, still no help.

I have logged probably 10 faults on my line for the past 5 weeks, still the problem remains. Everytime I get told, Axxess has escalated the problem, yet nothing happens, I continue to pay for a 20 mbps line, that's has been synching at below 10 mbps. This is pathetic service to say the least!!!!
