Bank happy to charge but unresponsive to reason or requests

Standard Bank are very quick to harass and intimidate when it comes to collecting on debt but when we have requested on numerous occasions for a debit order to be cancelled so that we can pay a bond from another account, they simply refused, leading to a monthly pile up of bank charges which have led my partner so deep into debt, he cannot even use his own account anymore and he cannot even afford to close it. Now they cannot communicate or respond to our requests, but otherwise they are happy to bully you. These are not bankers, they are banksters, who don't give a damn where you are supposed to get the money from. A terrible bank. I regret ever having taken a bond out from them.
