Payment rejected- using master card

I don't know about any of that, but your account has no books purchased at all connected to it. So that means you never bought any books, so nothing to cancel.

If it's a prepaid debt you have to call your card if it not stated on the packaging if adult products are allowed. If not then call your bank or credit card company to see if they received the transaction info and if they blocked it for fruad reasons.

You said "im gonna cancel my purchase of the books I rly wanted...".
Saying you're going to cancel your purchase implies you already bought them. If that's not what you meant, you may need to rephrase that.


Nitpicking aside,


Exaggerating a situation because you're frustrated isn't going to help.


This seems to be an isolated case since nobody else is posting about payment issues at the moment. So suggesting that your declined card may be the problem isn't "accusing" you of anything or "mistreating customers"; if a card is declined it's simply normal practise for the customer to first check that their card is valid, has money on it, and that their bank will allow the transaction. You've made sure that they will allow it, or at the very least they don't know why it's getting rejected, so that's a start.


And do you have any money left from that? No money causes declined transactions.
Is it still in date?

I had the same problem as you before, it began when I thought I had enough money in debit card but in fact I didn't, so I repeatedly submitted until I realized I didn't have enough money, I made a deposit, tried again but transaction was continually declined.

Repeating submit your request only made it worse, and because my debit card link with bank account so I just used another debit card that isn't link with my bank account. For the card that have problem, I just submit again after 1 month.

Depending on where you live, you might need to open up your card to allow for online purchases. You might have to do this even if you've bought goods online from other stores in the past. Similarly, certain banks have a minimum amount for online payments, which is why we introduced the tiers for subscriptions. If you've only tried to buy one month of subscription or a single digital book, that could be the issue. I don't know if either advice will be of any help, but that's two problems I've come across in the past.
