These are the four main misty reasons why you received a chargeback
As a merchant, you have to be fully aware of the most common reasons why merchants receive chargebacks. These are the circumstances that you also need to avoid at all costs. Note that most, if not all, chargebacks are initiated by cardholders. These are primarily due to inconsistencies in their credit card statements.
Fraudulent Transactions The most common cause for chargeback is fraudulent transactions. This happens when the credit card is used without the authorization and consent of the cardholder. In cases like these, the merchant is held solely responsible.
Credit Not Processed Another common type of chargeback occurs
when the customer may have returned the merchandise to the merchant (e.g. when the cardholder receives an item different from what he expected), requested to get their money back but said credit was not posted to their account. In these situations, merchants are also held liable for the charges.
Item Not Received This is one of the most commons reason for chargebacks today. This happens when the customer did not receive the item which they paid for by credit card. As in the previous situations, the merchant is charged accordingly.
Technical Problems Many chargeback requests are due to technical problems during the payment processes. Technical problems between the issuing bank and the merchant may lead to cardholders being charged twice for the same transaction (termed as duplicate processing). Problems with the authorization process can also lead to account being charged, even if the transaction was declined.
These are the four main reasons for chargebacks. There are a few more detailed reasons, which can be attributed to situations such as faulty cards and human errors made during the payment process. These cases, however, may be beyond your control as a merchant.
