How to avoid losing money and paying to fix a flat tire
When searching for a car sometimes, you will end up getting a flat tire and you end up being someone like me I don't pay for cash in the game. If you continue on trying to pay for it you want the payment method to decline because it will switch to the AppStore or something like that but when the screen flips push the home button and then double click home.
