If you never gave them authorization to speak to your parents then they are not allowed to discuss any legal matter with them. They can identify themselves if your parents asked them who they are, but they cannot say they are calling to collect a debt- this is a clear violation of the FDCPA. As for threatening to have you arrested, there is no such thing as debtor's prison, so I don't even know what they are talking about. If they have a judgment against you, there are ways of getting a warrant for your arrest for contempt of court (for failing to provide your personal asset information for example), but discussing this with an unauthorized party is also illegal. You may want to consider filing charges for violation of the FDCPA. In many cases, if you owe less than $1000, the collection company will just drop any action against you if you drop the action against them. As far as you payment plan, did you sign anything that said if you fail to pay judgment will be entered against you? If so, did you miss a payment? If that's the case, they may have gotten a judgment against you, and sent you an information subpoena that you failed to answer... so there could be an order or warrant for your arrest.
