Cheque Account

I opened a cheque account last year October, I went to close it off in December last year, cause I didn't like their services, I saw one of the consultant cannot recall his name, explained to him my reasons why I no longer need their services, told him that I have moved my account to another bank, he Was busy on the computer and then he told me that it's fine I can leave it's sorted, as he was rushing to go on lunch . A month later to my surprise I received sms stating that my debit orders has failed, I went back to the branch early January 15, was told to pay R900,before they can close my account, I refused as I have explained the situation to him that I am coming for the 2nd time for this, it's not my fault that they didn't do their job by closing off the account in time, I didn't not pay I am not going to pay I don't owe standard bank, today I received a call from some attorneys demanding R2000,00 from me when I ask them what is it for they can't even explain they saying I owe standard bank, I will be taking this matter further to credit ombudsmen and to news papers, standard bank like to make easy money with people. I am not rich I don't have money to give to you guys.
