Standard Bank - Account closure - Horrible Service

Over the past few months I am struggling to close my standard bank accounts and I am still not able to do so. I have asked for a settlement amount about 5 times and paid it each time. The last time I paid the settlement amount the gentleman told me that the account will be closed and now my account is still in arrear.

I have phone them again today and told them the situation and all I get is "we are sorry for the situation". I asked them for another Settlement amount and they told me I need to phone in 5 days later because the system can't calculate it today due to my statement closing on the 7th. All I want to do is close my account. Now I know I made a great choice to move to another bank! Horrible service offered to a client that had an account for 10 years.
