Citibank review: Deceptive billing practices

I was a new card holder I was waiting for my statement in the mail. I never got it in the mail. I called customer service to see if they had the right address. He told me the statement was sent on line. I said I never approve to go paperless. I never go on the computer or use my phone for any business dealings. He then told me that the payment was late which was two days late. I told him I would pay the total on the phone of $3,000 to wave all late fees. If it had sent it in the mail, I would have paid it on time but I never saw the bill. All the charges which is a FINANCE CHARGE for my $3,000 of 76.99. The Manager said it is auto dump charge they cannot override the system. It is Citi Bank inability to do their job in the first place, the cost I had to pay for. This should have never happened. This is deceptive billing practices. This company keeps receiving compensation of scheming victims out of money for these finance charges.
