I contacted eircom (through their web based customer support form) again about my credit refund and they told me (by email) that it takes 6-8 weeks to sort this out. I emailed back pointing out that my switch to UTV took place in February so this refund is long overdue. I have not heard back from them again yet. ComReg told me to use eircom's complaint/customer support process first and to get back to them if I got no joy. So I may be contacting ComReg soon...
