Pleasant Surprise!

I payed all my bills online today, but when I went to pay our electric bill it said we owed $0.00. I was very confused so I looked a little closer at the bill and it said that we actually had $0.60 in credit?? I knew there must be some mistake, so I called the 1-800 number to check it out. Come to find out that I had double paid last month on accident! It was correct, no electric bill for this month :) I love pleasant surprises!!
