Csaba Stefan's Everyday Consumer Experiences – The Good and the Bad

On this page, I share my real-life experiences and interactions with various companies and service providers – from telecom operators and car repair shops to software vendors and internet providers. I document both the positive and the negative sides, offering an honest look into what consumers go through.

This is not about complaining – my goal is to share insights so others can avoid pitfalls or discover great practices. These are not expert opinions, but personal stories based on real situations, often involving long, winding processes to find a solution. Where applicable, I also include how many hours I spent explaining and resolving the issue. These are the kinds of cases that tested my patience, spiked my blood pressure, and may have even contributed to a few gray hairs – for real.

Real Stories, Real Lessons – Learning Through Everyday Challenges

We all face service-related issues at some point, and often it feels like we're alone in those struggles. This site presents real-life cases that show how – or how not – problems were solved, and what valuable takeaways we can draw from them.

I'm not a lawyer or industry expert – just someone who documents their journey. Some stories are based on months or even years of emails, calls, and meetings. My goal is to help others steer clear of the same traps, and offer ideas for more effective problem-solving.

BCDR and IT Operations: "Show Me the BCDR!"

"Csaba, what should we do?" – a question I heard a hundred times in a few days, and when I asked for the BCDR, the answer was almost always: there isn't one, or it's out of date.

Cordia Woodland and the Miele Cooker Hood – 90 Degrees, a Saddle Fitting and a Shared Riser

Miele's service refused to connect the DAH 4980 cooker hood because of a 90-degree connection. First "a T-piece as per the design", then it turned out to be an angle-ground hole, silicone and a saddle fitting. Airflow calculations and a shared riser of about 180 mm for six flats – with odours and whistling.
