Looking for a new bank? Standard bank isnt it!

I rented a car from Hertz for 2 months, who deducted R9000 from my account on the 2nd month, and they shouldnt have. I contacted them and they said I need to contact you guys, which I did, then I was told Hertz needs to contact them, which they did! I started this whole communication with standardbank on 31 January, its now 12 February, and today Im told I need to contact Hert, again. THIS IS TOTALLY RIDICULOUS!!!!! Im in a minus of R6900 right now because of this, yet standard bank is relentless to threaten me to pay for my account. Im at such a loss for words right now, and so angry at this pathetic service, and all this from the pretige department. I'd really like to get this sorted out, as This money was suppose to be for petrol and food. Perhaps I should not pay my debit order to recoup this money, then Ill conveniently take my time to sort thay out too.
