The time on statute of limitations starts when the bill has gone into collections

If you paid on time for 4 years, and it went into collections 2 years ago, they have 4 to 6 years more to attempt collection. They try to get around it by selling the u collected debt to other collectors who falsely try to restart to 6 to 8 year statute time limit. They cannot call, or sue after the original time has expired.
