Reversal Of Funds

I mistakenly transferred money to a wrong account...my bad. Called Capitec Bank asking them to reverse the funds from the incorrect account (who's also a Capitec Bank client). I was told about the protocol and that it will take 7 working day. This was on the 25th of November 2015. Till date I haven't had any response, instead I'm the one following up and nothing gets done. I sent endless emails and still no response.This is by far the poorest service I received from any bank. I'm really flabbergasted by the way they're handling this situation.
