This started when I was a minor - years old, I 'm now -. - - which is now called -, they indicated I 'm past due in an amount of over $200.00 which I know I was n't. I was reported to Cheqsystems over 7 years ago and I have no idea how to get this removed so I can open an account. I 've done everything on my side to clear it. What now???
