WILL NOT ISSUE A CONFIRMATION OF AN INVESTMENT SHOWING FULL DETAILS

After a week of signing off on a Fixed Term Investment, the bank has still not been able to give me a written confirmation that includes the interest rate that was agreed or the term of the investments which was a year. I have been into the bank four times for the same problem - and all I get is 'that this is a TECHNICAL PROBLEM and all they can do is escalate it'! How is it possible that a bank of this size not be able to sort out their TECHNICAL PROBLEM in a week. I am very disappointed with ABSA with the handling of this issue. Although the branch staff are doing their beds - it is the HEAD OFFICE that seems to have the problem that cannot be sorted. I have reference numbers and ticket numbers for each call that the consultants made, but the problem still remains unsolved and they now have a very dissatisfied customer who is seriously considering removing all other investments and accounts from this ban****!!
