Over the past 18 months or so, I made XXXX balance transfers onto XXXX credit card. The interest rate on each transfer was 0 % until XXXX different expiry dates : XX/XX/XXXX XXXX, XXXX XXXX, and XX/XX/XXXX. XXXX This is the order in which they appear on the interest charge calculation page of my bill. ) I paid the minimum amount due every month until XXXX. Every month, that amount was subtracted from the balance with the 0 % expiry date XX/XX/XXXX. In XXXX, I paid an amount equal to the balance left on the balance transfer with the 0 % expiry date XX/XX/XXXX. Rather than subtracting that amount from the balance with the XX/XX/XXXX expiry date, the credit card company paid off the balance due XX/XX/XXXX, and paid down some of the balance due XX/XX/XXXX. I am now paying interest on the balance due XX/XX/XXXX. This seems very shady and bogus. Is that even legal anymore?
