Legacy Ld Intl ripoff Long Beach California

I received quite by shock a bill attached to my phone bill for $70.31, it states I used a calling card to call my home. I do not have any such calling card, nor did I make this call. I cannot reach anyone at the phone number on the bill to dispute this bill. I am calling my local phone company to have this bill removed, and, if there is any such calling cards out there for my phone they will be made inactive. I specifically have my phone set up so it cannot make or receive long distance calls.
