Integration Agency for doctors Scam??? (Hannover)

Hello good people! I am currently in Prague planning to move to Hanover soon, to start working towards getting a medical license to practice in Deutschland. I am working with an Agency that is based in Hanover and unfortunately I am a bit skeptical about this agency, for safety sake ofcourse. The agency is called Doc-to-let & the language school they work with is Sprachlabor Hannover.

And I was wondering if anyone would be willing to help me out and check if at all this agency and language school I am working with, actually exist. I checked on Google but I'm not convinced, cause it looks a bit awkward. I would really appreciate your assistance, as I am so nervous & I fear the worst! Thank you.
