Refund - cancellation of my order
I ordered iPhone 11 dated Dec. 23, 2021, and canceled my order on Dec. 25, 2021. I received an email for the cancellation of my order and it says 'they are processing my order' and also refund will be processed within 3 business days. Today is Jan 4, 2022 and upon checking my bank account, the refund has not been credited to my account. Pls help.
