Uninformed staff offering bad service

I visited Absa Andries in April to update my banking details and to request that my account be closed as I had opened an account with Old Mutual. I was initially assisted at Customer Service where I provided all the relevant documents and I believe that everything was captured on the system. I was then advised to visit the Teller department to close the account. A guy said he would process my request,he advised that I should withdraw all the money in the account before month end as he will be closing it then. I gave him all the documents and left the branch . Before the month could end I did as I was instructed. In May I discovered that the account is still active and owing , I then decided to visit the branch and was informed that I had to come back and close the account, a total contradiction to what the guy at the Tellers told me. I was then requested to settle the owing balance as the Bank is not at fault. I was disappointed and furious and left the bank. In June I visited the branch again to speak to the Manager, to raise my concerns and dispute the matter. The manager insisted that I have to settle the debt , she can only place a hold to prevent an accumulation of charges. I am a pensioner with a family to take care of, with lots of commitments, so I can therefore not afford to settle the debt. Secondly I feel that the incident was caused by uninformed, unprofessional employees. The whole experience has caused me some stress, I am very disappointed in Absa Andries Branch.
