SourceGas is making headway with billing problems, at least for one customer.

Keeli Magrum has been fighting with the Wyoming natural gas provider since her bills stopped making sense nearly eight months ago.

"You should always be able to add up the numbers," Magrum said. "And on these bills, the numbers just didn't add up."

Recently, Magrum has noticed a marked improvement in the way the company has handled her problems. Helen Wells, a customer service manager for SourceGas, began calling her regularly after Magrum reported her continuing problems to the Wyoming Public Service Commission.

Last week, Wells presented Magrum with a spreadsheet of numbers.

"It was disconcerting to see that the spreadsheet didn't say what my bills did," she said. "I didn't realize that the bills weren't printing what was on my spreadsheet."

While Magrum said she knows it would be nearly impossible to provide a spreadsheet to every SourceGas customer, it would be helpful in letting customers know how to handle their problems.

"That's what finally put my mind at ease," she said. "It made a world of difference for me to be able to go through and add the numbers up myself."

The spreadsheet hasn't solved all of Magrum's problems. She still has no "concrete evidence," since errors are still evident in her bills.

"I'm still waiting to see what's going to happen," she said. "It seems like the issues are getting better, but it still sounds like they have a way to go."

Other customers, while less satisfied with the attention they've received from the company, are hopeful that the situation is moving toward a resolution.

"It's not quite as intense as it was before," said Chuck Adkins, a customer who has experienced problems with multiple bills for rental properties he owns in Casper.

"At least they're contacting us now," said Kenny Thoen, who hasn't received a bill from the company since September 2007.

Representatives of SourceGas told the Wyoming Public Service Commission on Thursday the company is making progress.

Still, billing problems remain for 125 multiple billing customers (customers who receive bills for more than one residence) and 48 individual customers who have not received bills for a number of months thanks to a "human error" issue.

Len Mize, a SourceGas representative, said the company hopes all new billing problems will be solved by the end of May.

"We need to do what we need to do for our customers," Mize said. "We need to keep working toward getting all these bills accurate and timely and i think we're getting close."

Magrum said that even through continued worry about her bills, she's trying to stay positive.

"I've been angry and frustrated and upset about this situation for so long that I just can't do it anymore," she said. "It's not like they're doing this on purpose. I feel like they're trying to reach a resolution and I'm focused on trying to help them get to that point."
