Agreed amount not debited

<p>I have a Nedbank credit card I fell behind on as I was not working. When I started working I spoke to their legal team and their lawyers and signed some forms where I agreed to pay R500 per month. They said it was below their amount to accept but that they would accept it and monitor my account for 6 months. Imagine my shock when a debit went off of R889?????? I'm a single mother and losing an extra R389 is a lot of money for ne. Nedbank I trusted you when I signed those forms. Imagine my disappointment and shock that such a large financial institution can go back on their agreement</p>
