He wants ComReg to appear before the Oireachtas Communications Committee.
A midlands junior minister is calling on Eir to "drastically up its game" in providing support to its customers.
It comes after one elderly couple in Athlone says they've had no phone service for more than six weeks despite numerous calls and emails to the company.
Longford-Westmeath Fianna Fáil TD Robert Troy says he's aware of 10 similar incidents and is calling for ComReg to appear before the Oireachtas Communications Committee.
He says it's not acceptable people are unable to stay in touch with friends and family at this very difficult time:
This has really upset me. A constituent in his 70s has written seeking my help in getting his @eir service reconnected. He and his wife are alone - their children live overseas and they have been trying to get their service back for the past 6 weeks. pic.twitter.com/E57XdvsiWB— Robert Troy TD (@RobertTroyTD) November 12, 2020
