On one day last week after vodafone had done some maintiance (not sure where) i didnt have the lag problem until around 11pm and it only last an hour, And i did have any issues all weekend which u usually do, But the problem is still just the same and i spoke to one of your fault team this morning and ive just run pathping and tracert for her now as the problem is happening now.

She has also said there is higher than normal voltage on my line.

Sorry for the late reply
