Mr. Ed Morrissey CallsJun 13, 2016

Mr. Ed Morrissey On Phone To O2 Ireland Service
My number when I was with you was 0867770712 Ed Morrissey . I ended my contract with you and went on to pay as you go as I was moving country and just wanted to keep that phone going for awhile in case people from Ireland didn't have my new contact details. When I chose to go pay as you go I had to clear any outstanding balance which I did. I have just received a letter from a dept collecting agency acting on your behalf looking for the sum of €141. 66. This is not possible as I haven't been on bill pay with you for almost a year now. Could you please investigate this and get back to me ASAP.
