Terrible customer service once I lost connection for broadband. No connection between any of the customer service teams (eirchat, twitter, phone service, tech support). I have wasted HOURS of my life calling or contacting eir and no one seemed to be willing or able to help. Ridiculous timings set by engineers for visit (e.g. am or pm). Asked to speak to a supervisor a number of times and none available. No complains procedure which is available to the public. No apology forthcoming and I definitely won't be renewing my contract when it is up and will encourage others to do like wise if I am not contacted soon.
