Terrible service from Absa

Since April I have been calling and sending emails to absa bond department without proper assistance. My account went into arreas but no one can explain why. Every time I call, I go through the statement with them and when they see that the account should not be in arrears they promise to escalate the issue but nothing happens. I have gone through this nonsense over and over every month. These people can't even read their statement. When they eventually respond to my emails they reply with the utmost laziness. I can tell they do not even examine the statement. Mostly they say the account is up to date, once they told me that the account was closed. I have no more patience for this *******. If you attend a complaint, at least puts some effort.
