Wells Fargo Bank Took days to post my credit Denver Colorado

is that when you make a purchase when your card is swiped the store is electronically asking the bank can we debit this amount of money from this account. If you have the money, the purchase is approved, you get your merchandise and the hold is created. However, when the store processes the refund on your card, they do not contact the bank and ask can we refund the money. The store processes thr refund request and it can take 3 to 5 business days before the directive is received by the bank to put the money in your account. The bank does not hold any transactions but likewise can not post them until the documentation is received from the merchant. I apologize that this takes longer than you would like, but the bank has no control over when the merchant provides the documentation needed.
