UPDATE
Took them to the ombudsman. Virgin Media offered me full compensation for the delayed install and the dongle they told me to buy. They didn't even let it go to the decision stage (where they obviously would have lost). I also got my written letter of apology, as requested. This is after agents on here (Zach and Carley) assured me I was entitled to nothing as my install date was 'provisional.'
Advice to anyone who finds this thread and is in the same boat. Ignore the agents on here and over the phone who will argue until they're blue in the face that you're not entitled to any compensation. Stay calm and jump through the hoops until you get to the ADR stage. They're not on your side and just want you to give up and go away.
If more people stick with it and get the compensation they're entitled to, VM might have to start treating customers better in the first place. Good luck.
Well done in getting what you were owed. It is also useful to have your feedback on here for others to read in the future. It offers some encouragement, to those in a similar situation, that it is worth following through with the ombudsman.
That's the hope. So many must believe the agent's BS and give up.
Very well done and thank you for updating us.
