Planet42 out right crazy with an installment for a cheap car.

I did an application with a dealership and they said it will be about 7000 something per month. I was curious to do a application online and it shot out 4500. So i got back to the dealer and told them i got a message from them that it has been approved. and the amount is R7500 per month. I went to apply for a vehicle of R99 900 for 60 months . So if you work it out i will be paying R450 000 back total not evening the banks has so high interests rate ( I am not sure how they worked that out and i dont know how they see it can be 7500 per month on the installment. It is insane. That is day light ******* right.. I need a car but hell no will i pay that amount for a second hand vehicle. Some people get cars installments for way cheaper but this is out right crazy. I am sorry but Planet42 says one thing and then says another. i would understand paying extra 100k but 3 times the amount. thats is like going to rob a bank.. And plus they want a deposit of 9000 for what? no man... Planet42 needs to be audited and checked out because they way they conducting there business is out right crazy. someone needs to investigate them.
