I have no words

We made an arrangement the end of last year and paid the accounts off as agreed. We stopped all debit orders with the suppliers and then with Standard bank to. Standard bank was so kind as to stop the interest on the one account for 3 months But needless to say they have allowed a few debit orders to go through this account after we stopped everything. To add to insult they charge us R115 per RD on the account. I have been wanting to renew the arrangement for another 3 months but guess what - I don't get a response. I honestly don't know what to do with this issue anymore. I have never come across such an *********** bunch of individuals. Surely there must be something that can be done about banks firstly ripping people off with so much money and then also making money off individuals who can't afford it. It just seems they are not prepared to meet you half way - we are more than prepared to pay this account. We just need some confirmation and also if anything is stopped on an account to actually now allow it to go through - what more must we do?
