Poor service ****mers

Hi. i app**** with 42 in July, got approved. Signed the contract and 1st stallment was due end August. Paid successfully. September comes along and installment deducted again. On the contract it states the amount on 1st instalment date and not monthly instalments. I then called to discuss the instalment and wanting to cancel the contract or negotiate the installments, of which they not budging. Vehicle Price: R139000.00 Dep: R4000 Installemnt: R9400 Period: 60mth. Now please tell me with such installment i will pay the vehicle 4 time the price. to cancel they demand a 6mth installment. they not even prepared to neg on the installment as of now i cannot afford such a high installment. that to me with calculations made is pure unacceptable and would not recommend these people for vehicle finance no mattter the situation as they exploiting the situation.
