They helped scam me out of money, that never existed. A person I trusted gave me a check to help me in my business, I deposited the check in the bank, and waited for the bank to clear the check, (That was a big mistake) I was under the impression that banks have the capacity, to spot a bogus check. But I did withdraw a small amount on the check, but they held me responsible for a check, that had no value
