APEX, N.C. (WNCN) — Homeowners in Apex continue to be alarmed about high utility bills, with the town still navigating the aftermath of a cyberattack this summer. "I have no idea what to budget for," said Jennifer Carleton. Carleton just received another hefty bill. Man accused of threatening FEMA workers in western North Carolina speaks out "We made our payments and it’s still high and I don’t know if it’s because it’s not reflecting the payments we made before, but even after making the payments, it’s like $600," she said. Concerns over utility billing began in September, months after a cyberattack crippled the town's utility billing software. As a result of that attack, the town couldn't gauge actual usage, telling customers to pay their typical amount. When bills arrived in September, they reflected usage from June through August. "It’s very difficult to separate which is from what time period," Carleton said. Apex Town Manager Randy Vosburg says the bills customers just received this month still show a longer billing period, which has caused a new wave of questions. "We kind of have to go back to, okay here’s your bill from May, June and kind of rebuild it for them, and then once they hear the explanation, no one feels good about paying a bill, but at least they understand where we are in terms of why their bill is at the price that it is," he said. Rates are also higher now. Electricity is up 14 percent, while water and sewer are both up 4 percent with those increases taking effect in July -- at the same time as the cyberattack. But even with the rate increases, Carleton still thinks her bill is too high. "Now I don’t know if I need to budget for $50, $100 more every month, which is a really steep price if our usage is not changing," she said. The town says no accounts will be disconnected or penalized while these concerns continue. "We want to get it right and so we’re happy to talk to anybody who thinks their bill is higher than it should be," Vosburg said. Vosburg says the town is still in the process of hiring a company to conduct an independent review of the issues — and it's still not clear what the review will look like, or how long it will take. The town says Apex customers concerned about overpaying can also opt out of the bank draft.
