Avista Utilities is urging customers to be alert for a scam making the rounds. They say you should be wary of anyone who shows up unexpectedly at your home asking for inside access or uses high pressure tactics to demand immediate payment to avoid having your service disconnected. Avista employees and contractors must always display a photo ID badge, and all Avista vehicles and contract vehicles also have the Avista logo. Avista says their employees will never ask customers to purchase a pre-paid debit or credit card to make a payment.
