This is a bit of a saga and I feel that I am trapped in the ninth circle of hell so I will try to be as succinct as possible. I am ready to beg if that's what it takes to get someone to help.
An Openreach engineer needs to access my parents' property to investigate a fault which developed on 18/11/18, leaving them without an landline. talktalk have refused to make the appointment with me, insisting they will only deal with the account holder. My dad is the account holder. At this moment he is in ICU following emergency surgery at around 01:00h this morning.
