Hi tjhooker.
That seems to be an unacceptable amount of time to be without the line been repaired. Because they are with Vodophone it would have to be reported to them ,not to Eircom, which I imagine was done.
Speak to the Ombudsman as I am sure that if it is not repaired within, I think, is two working days they are entitled to credit. I know that getting the line repaired is the priority. Or if you live near a depot , see some of the eircom guys.
Hope its repaired soon for them.
