Ryobi Tools Refuses Refund Despite Order Cancellation

I'm dealing with a really annoying situation where the seller canceled my order for two Ryobi ACUU+ chargers, but they won't give me a refund. Even after multiple attempts to reach out via email and phone, the refund still hasn't been processed. I need a refund for the product right away. Here's your order reference: PTT-7M6S9FV1F-121023.
