Eir complaint: TV service disconnected for a week without notice or agreement

Last week (Thursday 28th April) Eir changed our broadband cable from a phone line to fibre – a positive and welcome development.
The landline has not worked since then, but that is not the main issue here.
The fibre installer’s attitude was curt at best, and unhelpful, but that is not the main issue here either.
However, on the same day, without telling us, Eir disconnected our Eir-Vision TV service, and we have not had TV service since.
We were told that the replacement box, and Apple-TV box, is with the courier. One week later, we still don’t know when this Apple-TV box will arrive, and Eir have washed their hands of it by simply giving me an email address and tracking number for the courier, and telling me that I am the courier’s customer, and the issue is between the courier and me.
The courier tracking webpage (extract attached) says that it will be out for delivery withing the delivery service timeframe that you requested – this is bogus in that we did not agree to be without TV service for any length of time, certainly not over a week.
