I went in on March *th, into the Lab Corp location at *** Post St, Ste ***, in San Francisco for blood work, I gave them my current health insurance card, that the receptionist photo copied. But instead of billing that insurance someone was lazy and sent the bill to my old insurance company without noticing that my insurance has changed and of course it was rejected and I'm getting a notice to pay $**.**. I've tried calling that office and they do not pickup the phone. I've tried calling your *** * and you give no options to resolve billing issues. Please contact me ASAP so we can resolve this issue.**thank you *John (Jeff) Rabb*member *(old)W************member *(current)********* with United Health
