Bad service

I went to absa wonderpark branch on the 18th of February regarding an investment that was maturing on 20th of February, I requested that on maturity the investment must be changed to a shorter term and I was told it is impossible. I then asked that the account be closed on the date of maturity and they said that it also impossible, the consultant said I will have to come back after the account has matured as it won't be re-invested immediately. Today 1st of March I received a letter saying the funds are re-invested for a further 5 years, I wanted to reduce the term to 3 years.
