incompetency and pathetic services

About 3weeks ago I went to Absa Phalaborwa with an interest to shorten the term of my personal loan from 3 to 2 years. Having paid for a year, I wanted to pay the remaining amount over a year. Like any reasoning person wanted to know what amount I would have to pay once the term had been shortened & I was told that Absa could not project the amount I would have to pay. This is very absurd as I have been deprived information to make an informed decision. I was told by enquiries that Absa is able to shorten the term however cannot project the amount due to inflation. I am livid as I cannot go ahead without knowing what amount I would have to pay, this looks as though Absa is depriving me the opportunity so as to maximise the profits out of this loan. This I was told after having spent a good two hours in the bank.
