Dissatisfaction of service

I had loan agreement with African Bank, my first concern was when I took out a loan I was required to pay for my first installment on that same month.

They kept on continuously harrasing me with calls to pay that outstanding amount of that same month I took out a loan, until we resolved it - only because I kept the communication they sent that I was suppose to pay the following month.

I have paid all my installments on time, until I made an early payment in July - big mistake. They debited my account again which made it two payments they later denied the second payment claiming it was my bank but the statement they sent me in August said reversal; a reversal that never happened even.

They have recently contacted me, a very fast speaking consultant extremely arrogant doesn't want to listen - I even told her that she wasn't giving me a chance to talk.

Apparently, I have two installments left not one for December because I failed to pay in October. This is the same bank I paid earlier this month and they sent communication that my balance is R1300 roughly.

I even told the consultant that I sent emails regarding this issue but they have failed to revert. How I owe 3k now is insane.

Such a terrible first time experience for me ! Remind me not to take out any loan with them again.
