Most of the time we will get our paypal transaction in our bank account within a week, some times it takes more days due to various reasons. In some cases bank may resend our money to paypal due to some issues and we are in need to pay 5 dollars to paypal for this kind of reversed transaction.
If it takes a long time to get your paypal amount in your bank account, just send a message to paypal via their twitter @ask paypal. They will check the transaction and send the reply to us, otherwise contact your bank about the transaction. For me the better choice is contacting the paypal. The customer service persons in paypal's twitter support is very friendly and help the clients in time.
Last month one of my transaction is reversed by my bank due to the bank issue. I sent a message to paypal and they suggested me to use another bank. After that i changed my bank, now i am getting money in my bank without issues. First of all we must contact our bank branch and find out they are having smooth transaction with paypal. Some bank branches always gives some unwanted issues with paypal transaction, better to change your bank if you have this kind of issues.
