Overcharge on interest

I would give them a 0 if I could.

I have the Sanlam Money Saver Credit Card. They have been charging interest on my account incorrectly, as much as 50% interest. The call centre agents do no allow you to speak to a manager. They are always in a meeting or going into a meeting. You ask for a manager to call you back and get nothing. The consultants only feedback is that they are busy with the accounts which were overcharged, and Sanlam never even communicated this error to clients - they kept quiet, so only when people are calling in to query, that's when they'll look at your account. It's been more than a week and I still have no feedback and I still can't get to speak to a manager.
