VAF -TREATING CUSTOMERS FAIRLY IS NON EXISTANT

2 weeks ago i called the VAF call centre, asking them when is the latest date can i deposit money to lower my installment. They advised on tuesday or before the 20th. So i deposited the money and it was reflecting on the 18th Feb. I then called the call centre to recalculate my account. I called on the 22nd and 24th of feb and both consultants could not even give me my new amount. On the 24th the consultant told that the new amount will be deducted today(25th) but he could not give me the amount. Today i get the same amount deducted and i still never even get a email regarding anything. I want standard to debit my money back to my account and debit the right amount. If this is not resolved will be going to the ombuds.
