Absa charging for an unused account.

About 18 months ago I went to Absa Centurion mall to open an account. I specifically asked for an overdraft facility, as part of the transaction. They opened the account, and I had to deposit some money. When I went to collect the card, I enquired about the overdraft that was supposed to be part of the package and was informed that it was not approved. I told them to close the account as that was part of the deal. Fast forward a year and I start getting threats from MBD attorneys for R1618.40 for my Absa account which I never used. I told you to close the account. I will not pay for an account that you did not keep your promise on.
