I made the big switch from ESB (in my name) to Bord Gas Electricity (in my husbands name) back in 2009 when it first came about. I have always paid any bills I receive as soon as I can as I hate having bills hanging over me. Just recently ESB contacted me to say there was a balance of €113 owing on my account from 2009. But, I never received this invoice or any reminders or statements to say this was owing. How can they do this after all that time? I can't prove it was paid as I have no receipts as I only keep them for a year or so. But, i truly believe I don't owe this. I contacted them and they didn't want to hear what I had to say and then I got a letter from a solicitor saying legal action will commence if I don' pay the bill. Do I have to pay this or is there anything I can do?
