I've been receiving letters from Debt Recovery Solutions claiming that I owe Verizon Southwest $292.69 for cable/cellular service. I don't even use Verizon for cable/cell, only internet and I've never missed a bill. And the account number they referenced is not even mine. Worst of all they reported this as a deliquent account and is negatively affecting my credit score, lowering it by almost 100 points. Anyone experienced this before? Do I need to get a lawyer to resolve this?
