I’m thinking of suing the utility companies for not notifying me of non-payment creating unsafe/ unsanitary situations that led to house fire, thousands in damage.

Always good to know of other companies who provide products and services!

The lender did not use a servicing company, and the pay history is being contested (which should be easy to prove)2.

There were platinum and non-platinum plans. 

The servicers have to send notices 15 days prior to the transfer, but the new servicer is required by law to honor any payments made to the old servicer for 60 days.

If they say Service Link, find another house.

Service seems useful.

I spoke to them about 1.5 months ago and since then they have been non-responsive that makes them look like not the real deal and I'm wondering if they are still around and active and good?

I am not aware of any issues with using third-party screening services. 

It's possible to buy property in Germany with as little as 5-10% down, making it an attractive option for service members and civilian government employees stationed there or planning to settle.
