Hi, new here but desperately need some info. Got a demand for money ($1814.25) from Portfolio Recovery. Went to verify on credit report, found the same account with the same "status updated" date with LVNV. But here's where they differ. LVNV is (same account #) for $467. So, should I infer from this that Portfolio Recovery got this from LVNV(?) and decided to up the amount by 4x? Now I don't know whether to dispute the debt on the credit report, send them a debt validation letter (which I've read bad things about) or just wait to see if they take it to court (where I can dispute the amount)?
