请教柠檬和各位大拿：被subrogation联系要租客的identifiable information

事情是这样的：去年我的租户的洗衣机漏水，导致出租房被淹了。我通过房东保险拿到了赔偿。我的保险公司问我房子被淹的原因，我如实告知了他们。然后他们要求提供我租户的rental insurance policy number和租约，我也提供了这些信息。现在Subrogation Service给我发email，说

“xx insurance has referred your claim to me for subrogation. We are attempting to get reimbursement from your tenants xx and xx.

I would appreciate your assistance and am seeking any application or identifiable information you may have for them. We had that they were insured at the time of the accident however have not responded to their insurance company.

I appreciate any information you could provide."

看起来应该是我的保险公司找租客的rental insurance company赔偿，但是租客没有配合他们。我的问题如下：

1. 现在我是否应该将租户的application给subrogation？application上面有租客的SSN和driver license number，把这些给subrogation是违法的吧？

2. 我应该怎么给subrogation回信呢？还是就不回信？他们一个月前发了email，我一直没有回，昨天subrogation又发了一遍给我。

3.subrogation service会一直找租客赔偿吗？我拿到的赔偿金是两万多，租客手头不宽裕，估计拿不出两万多。那我明年还应该跟租客续约吗？

谢谢各位！
