Made a payment on the first and I received an E-mail confirming payment and said it has posted! Two weeks later I receive a bill stating that the payment was declined because of insufficient funds. Columbia gas waited a week before they submitted the payment and apparently my account didn't have the funds available at the time because I wasn't aware that they did not submit it untell a week later when my account did not have the funds then! So they charged me $18.00 dollars extra for process
