Northland is a debt collector - I have had dealings with them - they should be covered under the C&D, VOD laws, etc.
Also as to this writing a letter to the OC becfore it goes to CA - how would this work with a run of the mill credit card (visa, mastercard, dept. store, etc.) I thought you could not VOD an OC? AS soon as you dispute it - they can usually validate it with all your bills, etc.
A bit confused on this one
