@john_k_tsai -- have you signed-up with Shaw to automatically receive payment, via your bank account or your credit-card?
Where are you seeing the two charges? via the My Shaw Portal, or via your Online Banking ?
One month, a few years ago, the "automatic" billing was declined by my bank -- incorrect account information. I suspect that a Shaw employee, not a Shaw computer, processes those "automatic" charges, and the employee made a typo when submitting the transaction.
