Will I get refunded for incompetence?

On the 5th May I called the Discovery card division to make arrangements as I was only going to be able to make part payment on my credit card this month, having been ill and booked off work for two weeks (for me it's no work, no pay). I had paid R1000 and the call centre gentleman told me to call *** on the 12th May to make further arrangements. I was told not to phone immediately as they wouldn't be able to assist. I called at 10h10 on the 12th May and waited as \an operator would be with me shortly". No answer. I tried 4 times until I got a message to leave my name and number and reason for call and someone would get back to me. That didn't happen but this morning I get an sms from the bank - Discovery had taken the balance of their money off as a stop order and now I have to pay overdraft penalties! <br> <br> Would someone who actually knows what's going on please contact me urgently!<br> <br> <br> """
