Any agreement on your part to get on a payment plan transforms the old, low-value debt you incurred with your credit card into a *brand new*, *high value* debt that you owe to the bill collector. There's a good chance they'll sell this debt to another collector and take the lump sum - and then the new collector will commence a fresh round of harassment.
McKenzie says you should *never* talk to a debt collector. Make them put *everything* in writing.
