PayPal Bank Account Or Service Complaint

PayPal Bank account or service department,

Other bank product/service Deposits and withdrawals Missouri

I sell on -. I have to use paypal as part of their requirements. Paypal when you purchase something takes the money immediately out of your bank account. However when depositing they take sometimes up to 6 days if it falls on a weekend. Then my credit union holds the money sometimes a day. I buy and sell so not having my money in my hand is hurting cash flow. I believe this holding money is a significant drag on the economy and there is no justification for such a long delay. The banks also do this when wiring money from bank to bank or processing a refund on a debit card. Is there a law that limits them. Is there anything you can do to speed up this process. Thank you
