Why was my credit card declined?
You should probably contact your bank in this regard. You can pay by credit card, PayPal, or Crypto as Bitcoin or USDT, for subscriptions.
Why is PayPal asking for my card?
Paypal is asking you to register your bank or credit card account in case your PayPal balance is not sufficient. Paypal always tries to debit your balance in priority; if not, it will use your credit card or bank account. If you have enough funds in your PayPal account, it will use them to pay your subscription.
Why did my payment not go through with PayPal?
There are various reasons why a transaction wouldn't push through with PayPal. Here's a good resource for those failed payment reasons: PayPal payment error reasons.
What if my PayPal renewal didn't go through? Will it try again?
If you have paid with PayPal, the system will not try again to charge your account. You have to wait until the end of the 48-hour grace period to renew the plan, or you can directly subscribe to a fresh new pack.
Why hasn't my crypto payment posted yet?
Please note that BitPay does have multiple network confirmations before we get your payment. If your transaction has gone through, but has not been posted yet, please give it 30 minutes to 2 hours for posting.
