How do I book an engineer to look at my parent's landline? It's very scratchy and can be hard to hear people on it.
They have it connected to the main phone socket via an extension lead as the phone's cord is too short.
AFAIK their TV and broadband are working fine so I'm guessing that the problem is likely between the brown box outside and the master phone socket
This needs a bit of a 'divide and conquer' approach, now although it is likely to be a problem at VM's end, it is just possible that the fault is with the handset itself or the extension cable. Both of these need to be eliminated first, so can your parents beg, borrow or steal* another phone hence to try? Can it be plugged directly in to the wall socket to eliminate the extension cable.
* no don't actually go shop lifting and literally steal a new handset from Curry's - it's a figure of speech, yes?
