Broadband intermittant fault. - 5th engineering call

[Tinaglen]

I have had poor broad band since January.  i have had 4 engineering calls to date.  1  new router, 1 new cable.   5th engineering call scheduled this week.   Thought it was fixed after the last engineer turned off a socket that may have been noisy.

I have spent 4 hours on the phone with sky in April alone. 

There seems to be no escalation, only endless call centres.
The last open reach engineer was good-- he was a brickwall specialist-- i..e hard to fix cases, but after 10 days, we are worse than ever, with the signal dropping every 20 min.    When diagnostics are run, it says all is fine (!)  We have unplugged and rebooted numerous times.  I cannot work like this.   Is there anyway to get someone at sky to really help??????   Or do i just need to leave after 16 years?  I am at my wit's end.

Unfortunately, switching to another Openreach- based ISP is likely to result in exactly the same fault becoming their problem but without any accompanying notes.

Sky, like any similar ISP, cannot 'escalate' an issue internally because only Openreach is permitted to touch the infrastructure.
