What is the name of your state? MARYLAND I'm in the state of MD. Have a couple collection agencies attempting to collect on an old cell phone bill. I know I can request a debt validation, especially since they can't agree on an amount, but the question is.... The SOL in MD is 3 years. Does this apply to cell phones? Are they the same category as credit cards? If so, do I need to go thru the validation and such or just write to them specifying the DOLA and for them to cease? Thanks!!!
