Jaxar: Hi, Welcome to the forums. Looks like this problem is well on the way to being cleared up. Thought I would add my 2 cents and clear up the confusion about how the Telecom Sales person tested your neighbors line but the VF faults tech could not.

The VF faults tech would have been using a tool that checks the actual stats on the line. He can do this as you are a VF customer. The Telecom sales person would have been using a tool which doesn't do an actual test but pulls some info from a database and gives some estimates. These estimates can often be wrong for example my personal internet connection is a good 5Mbit faster than the sales' tool estimate.
