HUB VERY QUICK TO BLACKLIST YOU

about 4 years ago hub blacklisted me my brother was using my card and because it was on my name I had to pay it which I did . I don't get any statement, or emails from them. beginning of this year I had a call from the call centre to say I still owe them R1500 - for interest???? really if the account was settled why is there interest and today I can not take a bond for this silly matter. I have tried to get an statement of account from them but from team leaders to workers are there no responds. Does it take them 3 years to contact me. I think its just an excuse to add more interest to make more money....
