ABSA and their GREED! A Greedy bank

I have sold my house, of which my bond was with ABSA. ABSA took more than R15000 extra to settle the bond. The attorneys said that ABSA took more, but will refund me. After several emails they have not responded or refunded me anything. ABSA IS GREEDY! I have given them more than 3months, thus I should not pay any penalties. I have found out, no other bank does this. Maybe I should take them to the Ombudsman. There is just no pride or something like customer services anymore.
