How long does it usually take for the credit to show up?
I have stayed one night back in December 21st at the Hilton Oak Brook resort. Not advance purchase. At checkout, because of processing error at the front desk they refund me $50 back to the card so it shows up as two different entry on the AMEX:
12/21/18 HILTON CHI OAK BRK H
OAK BROOK IL
Arrival Date Departure Date
12/21/18 12/21/18
00000000
LODGING
-$50.00
12/21/18 HILTON CHI OAK BRK H OAK BROOK IL
Arrival Date Departure Date
12/21/18 12/21/18
00000000
LODGING
$316.04
Will that refund somehow mess up the resort credit? How long I should wait before I call AMEX?
