Failureto close my bond accounton my instructions

After I paid off my bond I app**** for my title deed. The consultant advised me that the account should have a zero balance, since my insurance was paid into the same account. They advised me to open a new account for my insurance, which I did. And I gave them instructions to close the old account. They failed to do so. Now the premiums of the old account got into arrears due to their negligence. And they refuse to close the account before I pay the amount of R2259.22 in arrears. It is very unfair to pay two premiums, because of their negligence, and it is a lot of money for me as a pensioner. But I paid it on 9 Oct 2017 just for me to get my title deed. I have been a client of them for 34 years and this is the type of treatment I get. I am going to take my banking business elsewhere, where I will be treated with the necessary respect and professionalism. I am very disappointed in their service
