TD Bank US Holding Company Credit Card Complaint

TD Bank US Holding Company Credit card department,

Late fee Texas

I called Target RED card today ( - - ) to pay my credit card balance in full ( $60.00 ) and was informed my balance is now $86.00 due to me being hit with a $25.00 late fee. My bill was actually due - -, not the -. I explained that I was out of town and it just slipped my mind but with today being the next business day after the - holiday and next business day after my bill was due, I assumed that I would have a grace period of some kind. They insist there is nothing they can do to waive it and that even if I spoke with a manager or supervisor they could n't waive it either. I find this rather egregious and ridiculous that if I am a mere - days late, ( a holiday weekend no less ) that they will not work with me, especially when i am willing to pay my balance in full.
