Tips if Fraud is Suspected

1. You received an email from Wausau Supply Co indicating our bank change from Wells Fargo to Bank of America, with the only instructions to go to this web page and verify payment details here. Wausau Supply Co will never send you banking instructions inside an email.
2. Do not act on emailed banking changes, even if they appear to come from WSC and instruct you to pay at another institution or at another account than what is listed here. 
3. Compare any payment instructions against the details of this page. 
4. If they differ, DO NOT PAY - call us first. 
5. Confirm by calling the Accounts Receivable number on this page - not a number or link from an email.
