Very old customer, way back from NTL days. Recently moved 2 weeks ago. Transferred 200mbs service to a quieter area, and for 10 days perfect stable broadband service. Well over 200mbs reliable download - peaking at 220 at all times of the day.
In past 72 hours, my service is all over the place. Cant get above 75 now. Phone VM and cant see a fault in the area. Several reboots and frequancy changes - but no improvement.
