Is there a big deal about single billing? It doesn't save you any money (other than the bank charges associated with paying the bills, if any). We are still receiving Eircom line rental bills around 6 months after transferring to UTV. I've found their customer service to be ok to be honest, and aside for around a week of patchy service about 2 or 3 months ago, everything has been fine. Better than waiting for SMART/Eircom mess to be sorted out, but there are other packages that I will investigate when my 12 month UTV contract is up (e.g Magnet/Metro).
