Short Answer 
The error indicates a pending transaction that hasn’t been fully processed yet. It’s important to check your bank statements for any charges related to it, and if it remains unresolved, contact customer support for assistance.
Step 1: Understand the Pending Transaction
The error indicates that a transaction you made using a credit or debit card is still pending. This means the transaction hasn’t been fully processed yet, and your payment is awaiting confirmation from the bank. Such delays can occur due to various reasons in the payment system.
Step 2: Check Your Bank Statement
It’s important to regularly check your bank statements to ensure that duplicate transactions do not occur. Look for any charges related to the pending transaction and keep track of whether it has been confirmed or remains unresolved. This will help you manage your funds and avoid additional fees.
Step 3: Contact Customer Support if Necessary
If the transaction remains pending for an extended time, consider reaching out to customer support for assistance. Contact either your bank or the merchant’s customer service to inquire about the issue. They can provide information about the transaction status and guide you on the next steps to take.
