Just because it shows on your card doesnt mean it has “gone through”. Case in point: many gas stations charge $1 to see if its a valid card. That charge will go through and then just disappear.
Superpredator has tried to explain this, and i did as well. Obviously you know exactly what you think is going on. Your chargeback will result in your inability to order again. However if you would gave had patience PSA would have issued the refund once it actually went through (again, not immediate despite what your bank website/app says) and you would be good to go. You do you though.
