I was not treated fairly

On the 26 June 2015, One lady called from Motorite and explained that the service plan for my car (Nissan Navara) is been changed from 3 years deal/ 90000km to 5 years deal/90000. She did not explain to me that this is an upgrade. In my thinking i concluded maybe they have made the mistake in the beginning when I buy the car. She also explained to me that the monthly premium is included on my monthly installment.<br> Later I received the new contract to my surprise from Wesbank stating that my installment have changed by R839-00 which I was not aware of. <br> I sent the email to wesbank on the 15th July 2015 to notify them that I am not interested if I am to pay extra amount on my installment, they have to cancel that. They gave me the number for Motorite and I called where I found Divan who he have never stood in a position to help me. He send other people to talk to me. They requested me to fax documents so that they can cancel that policy. One that make me angry is that, I have to pay all the bank charges and my account is in arrears for their fault. <br> Nobody explained that when I cancel, my account will fall in to arrears. I am truly not happy and they need to update my account.
