My order was declined, but I just checked with my bank or credit card issuer and they say I was charged for the declined orders. Why is that?

Hi there this is my first time on this community, as the title said I was charged but the product wasnt confirmed I called wd but looks like I have to wait now, I was wondering if this has ever happened to anyone else before. The product I wanted to purchase was the new WD P10 8tb gaming drive.
