How long does consumer portfolio services allow you to miss payment before they repo?

I know that CPS bought my car loan from another lender, they are NOT the bank that I origionally signed with. However, less than a week ago my payment bounced. I am 4 years into my loan. I was not even aware of this until I recieved 12 phone calls while I was at work. When I tried to call the "manager" back on the number he provided he never answered or returned my calls. I called the main number and a man told me if I couldn't pay the payment today to clean out my car as it would be reposessed this weekend. (this happened on Friday) I told him I would call with the payment Monday morning and he said he couldn't stop the reposession order. I have had my car hidden for the weekend and will make the payment Monday morning, but this company is aweful.
