Ms. Sprengel is a very competent young lady with a lot of specialist knowledge. She takes time for her customers and explains questions until you understand them.
Appointments are also very flexible.
Definitely recommended!
Sabrina Sprengel has been advising me for several years and does so in a very competent and friendly manner. Scheduling appointments is very flexible and straightforward. I highly recommend consulting with Ms. Sprengel!
Free consultation with analysis. Identified potential savings, very competent, with no pressure to sign a contract.
Thank you, Sabrina, and I look forward to hearing from you again next year.
The advice is understandable, you save a lot of money, and it's free too :)
It's great that there are consultants like this who can help and support you with this topic of electricity/gas tariffs.
