Bank of America Credit Card Complaint

Bank of America Credit card department,

Late fee Washington

The - month I paid my BOA credit card statment - cents short. The 2nd month came with that amount due plus a : '' minimum interest charge '' fee of $1.00. I called, was told as a long time customer they would waive it, so paid my balance minus the $1.00. the 3rd month - the charge remain plus incurred another minimum interest charge '' of $1.00, called and was told the $3.00 would be removed, so paid the balance minus the $3.00 ; 4th month, got a credit of $3.00 but got another $1.00 minimum interest charge. '' This time I was told even though BOA was giving me credit, I had to pay the $1.00, because the credit would n't go into effect until after my balance w/the fee was paid. I would then receive a credit, which would then be applied to my future balance. Why? ca n't BOA, when they say they 're going to remove their charge, remove it at that time like they do other vendor charges that are being credited back? Thank you.
