In the case of the payment in "Instant Transfer from your bank account", Several days are needed until payment is completed.
We cannot ship until payment is completed completely.
I would really appreciate it if you understood my situation.

3. Sending Money.
3.1 Sending Limits. We may, at our discretion, impose limits on the amount of money you can send through the PayPal Services, including money you send for purchases. You can view your sending limit, if any, by logging into your Account and clicking on the View Limits link on the Account Overview page. If you have a Verified Account, we may increase your sending limits.
3.2 Default Payment Methods. When you make a payment, if you have not selected a Preferred Payment Method, PayPal will fund your transaction in this order:
Note: If you do not want to use your Balance, you can withdraw it before making a payment.
3.3 Preferred Payment Method. You may select a Preferred Payment Method each time you make a payment, except when making a Preapproved Payment, a No Log-In Payment, or an In-Store Checkout payment. Certain funding sources may not be available for certain products; if there are funding source limitations, these will be disclosed to you as part of your transaction flow for the specific product in question. For a Preapproved Payment or, in most instances, a No Log-In Payment, you can select a Preferred Payment Method when you provide your initial authorization for this payment and/or through the My Preapproved Payments section of your Account Profile (it may be called "Backup Payment Method"). For In-Store Checkout payments, you may change your Preferred Payment Method in your Account Profile prior to initiating your transaction.
If you select a Preferred Payment Method but have available Balance in your Account, your Balance will be used to fund your payment first. If you set a PayPal Credit product or eCheck as your Preferred Payment Method in your Account Profile, it will be used to fund your PayPal payments first, even if you have a Balance.
3.4 Payment Method Limitations. In order to manage risk, PayPal may limit the Payment Methods available for a transaction. In addition, Payment Methods may be limited if you make a PayPal payment through certain third party websites or applications. For PayPal Business Payments, you are limited to funding your PayPal payment with either (or both) your Balance or by eCheck. In all such cases, you may choose to continue with the transaction with the understanding that you may have fewer avenues available for dispute resolution should the transaction turn out to be unsatisfactory.
3.5 Bank Transfers. When you use your bank account as your Payment Method for any transaction or to initiate an Add Funds transaction, you are requesting an electronic transfer from your bank account. For these transactions, PayPal will make electronic transfers via ACH from your bank account in the amount you specify. You agree that such requests constitute your authorization to PayPal to make the transfers. Once you have provided your authorization for the transfer, you will not be able to cancel the electronic transfer. For Pay After Delivery transactions please see Section 3.15. You give PayPal the right to resubmit any ACH debit you authorized that is returned for insufficient or uncollected funds.
