TE's Third Party Repair Centre: SCS Servicecenter-Siedler

Anyone had any dealings with SCS Servicecenter-Siedler? TE have informed me today that I’ll have to use them to fix my OP-Z. Apparently SCS Servicecenter-Siedler will repair faulty OP-Zs that are out of warranty.

Awesome, thanks!
For me it’s literally around the corner.
