My wife mistakenly wrote a check from the wrong account and it was returned NSF. We immediately contacted the payee to redeposit the check and transferred the funds, which covered the entire amount. The day after the check was paid in full we were charged {$1000.00} by Qualia Collection Services ( QCS ) as a return check fee, which we have disputed. I attempted to speak with QCS to pay a reasonable return fee but the individuals I spoke with only responded that they are charging the maximum allowed by the state and that the fact that the entire amount was paid in less than 3 days did not make a difference. I was also threatened with a lawsuit if I did not pay the entire amount.
