Amazon currently has a massive glitch. When you cancel an order you can still be charged, I believe this will happen if the order has already been started and you cancel while the Order is being filled at the Amazon warehouse. Then it’s nearly impossible to get your refund. The transaction disappeared on my Amazon account but still shows deducted from my bank account with zero refund. Because the transaction disappeared from my Amazon account, there’s no way to get my money back from Amazon except to do a reversal with my bank. It’s a real hassle. I wish there was a better way. It’s literally causing me too lose sleep and so much stress. It’s been forever and still fighting.
