Mediation Recovery Center Debt Collection Complaint

Mediation Recovery Center Debt collection department,

I do not know Cont'd attempts collect debt not owed Debt is not mine Ohio

Four times in the last 10 years, a debt collection agency has written/called to collect a debt of a person who, by marriage, had the same first and last name as me. Each of the - previous agencies has ( after every excuse in the book ) finally left me alone. And then apparently sold off this issue to yet another agency. When & how do I get relief from this abuse? At no time has any of these agencies ever been able to establish that this debt is mine. But they have obtained my SSAN and lie to me, saying my SSAN was on this debt, threaten lawsuit and credit reporting, and say that since I can not prove that this debt is not mine, they will continue to attempt collection. Well guess what? If the debt is not mine, how could I possibly have any proof about the debt, one way or another?
