It occurs to me that you never said where your parents are apart from its a remote location in Wales.
I believe Openreach declared North Wales as a MBORC (Matters Beyond Our Reasonable Control) area at the end of last year due to the severe weather/flooding experienced there.
Usually MBORC's only last a few days but it think that the North Wales one may exceptionally still be in effect.
Even then, that doesn't excuse the PO for their continuous poor handling of your parents case - and it's the type of situation where properly marking a case as a welfare one would be even more important than normal
