why the delay, its inhouse

Im getting highly irritable with the debit date of my credit card payment. All my debits are set for the 1st of each month, depending on if its a workday i dont mind it going off the next day. Its bad enough i have to wait roughly a week from payday for all my debits to go off but iv noticed that my credit card goes off an average of 2-3 days later. Its not like its from one bank to a different one. Its the same bank. If i wanted ****ty service i would have stayed with standard bank.
