Discovery Bank - USELESS

This so called Bank is ******* and useless. I have had credit card with Discovery in year 2022 which i found useless and over charging even after you pay full amount. After realizing this ******* i settled in full and cancelled it within 2 - 3 months! Now after a year on my credit check it still shows i have credit card with Discovery for 10k Now it is affecting my credit score. What a useless bank - Would say that STAY AWAY FROM DISCOVERY BANK
