Creditors Interchange has bought my Chase debt.... is it safe to pay?

My Chase account recently got bout by Creditors Interchange... they are telling me that the are the representative for Chase bank, and have offered to take 30% of the balance. I do have the money, to pay them, and they said to make the payment to Chase Bank. Is this a legit company? If I send this check is it going to resolve my debt with Chase Bank? I'm afraid I might get scammed, pay 5K, and still live with this debt. Someone help!
