When you say Barclay's has stopped reporting, what does that mean. No data shown for the past 15 mos? In any case, you should take care of it. Call them up (assuming it's not with an external collection agency) and see if they'll take less,or offer them 300 to "settle for less" and see what they say. Have money ready though, if you poke the bear be ready to shoot.
